In two chapters this dissertation examines whether out-of-school activities affect behavioral outcomes reflecting character, social and executive function skills. The first essay in this thesis analyzes the effect of performing sports on a regular basis on the formation of character and social skills. The findings confirm that sports is generally a social activity. For youths from less advantaged family backgrounds sports constitutes often the only quality pastime they engage in. Athletic involvement has beneficial effects on a broad range of character skills. These effects are largely driven by youths who do not engage in any other structured activity. Further, the effects can be interpreted as a broader effect of having access to an enriched social environment. The second essay examines the effect of working part-time while attending full-time schooling on the development of character skills and occupational choice strategies. Comparing adolescents who hold a job with adolescents who do not work, the former spend less time in front of a screen and invest more time in academic learning. Focusing on the time use of employed adolescents, working part-time has an ambivalent effect on time invested in other activities. It reduces their homework time as well as their nonproductive screen time. The results imply that holding a paid job while still in school reduces the uncertainty about own interests and talents and reduces the dependency on parents. A third essay evaluates the impact of the Tenancy Law Reform Act in 2001, a policy which targets to protect especially low-income households against rent increase. Germany is one of the European countries with the highest percentage of the population who lives in tenancies. This illustrates the importance of a functioning tenancy law, socially and economically. This essay analyzes the effect of the reform on the level of rents as well as on the residency discount. The two substantial parts of the reform were the reduction of the maximum rent increases for sitting tenants and the reduction of the minimum notice period until termination of a tenancy by the tenant. Estimating the effect over the distribution of rents, the reform shows a significant negative effect on rents that is stronger at higher quantiles. The annual residency discount increases with the reform during the first three years of a tenancy and vanishes thereafter. The evidence suggests that the reform was successful in curtailing rent increases especially for expensive apartments early in a tenancy. This thesis provides a differentiated picture on how economic inequalities can be alleviated. On the one side, this thesis focuses on the formation of character skills which are helpful for bringing especially unskilled people into employment and to better paid jobs. On the other side, this thesis focuses on a tenancy law reform that targeted to protect tenants against rent increases. While beneficial effects of structured leisure activities on the formation of character skills can be detected, one may be concerned that the tenancy law reform may not have been sufficiently targeted if considering the target of the reform to protect especially low-income households against rent increases.', 'Diese Dissertation liefert ein differenziertes Bild zu zwei Interventionen und einer Politikreform um die ökonomische Ungleichheit zu mildern. In zwei Aufsätzen wird dabei auf die Rolle von außerschulischen Aktivitäten bei der Bildung von charakterlichen und sozialen Fähigkeiten eingegangen. Der erste Aufsatz in dieser Dissertation betrachtet den Einfluss einer regelmäßigen Ausübung von Sport auf die Entwicklung von charakterlichen und sozialen Fähigkeiten. Die Ergebnisse zeigen, dass Sport generell eine soziale Aktivität ist. Für Jugendliche aus sozial benachteiligten Schichten stellt Sport meistens die einzige qualitativ wertvolle Freizeitbeschäftigung dar. Sport hat einen förderlichen Einfluss auf ein breites Spektrum an Kompetenzen. Dieser Einfluss wird insbesondere durch Jugendliche, die keine anderen strukturierten Freizeitaktivitäten ausüben, getrieben. Zudem kann der Effekt von Sport als einen umfassenderen Einfluss des Zugangs zu einer bereichernden sozialen Umgebung interpretiert werden. Der zweite Aufsatz untersucht den Einfluss der Ausübung von Nebenjobs als Schüler auf die Entwicklung der Persönlichkeit und von Einstellungen und Strategien zur eigenen Berufswahl. Die Ergebnisse zeigen, dass Schüler, die neben der schulischen Ausbildung eine beruflichen Tätigkeit nachgehen, mehr Zeit in schulisches Lernen investieren und weniger Zeit vor einem Bildschirm verbringen. Jedoch verringert sich die Zeit die mit Hausaufgaben verbracht wird wie auch die nichtproduktive Zeit vor einem Bildschirm, wenn neben der Schule noch gejobbt wird. Insgesamt hat ein Nebenjob förderliche Effekte auf die eigene Unabhängigkeit gegenüber den Eltern und verringert die Unsicherheit über eigene Interessen und Fähigkeiten. Der dritte Aufsatz der Dissertation evaluiert den Einfluss der Mietrechtsreform in Deutschland im Jahr 2001. Diese Reform beabsichtigt u.a. geringverdienende Haushalte vor Mietanstiegen zu schützen. Im Vergleich zu anderen europäischen Staaten weist Deutschland den höchsten Anteilssatz an der Bevölkerung auf, die in Mietverhältnissen leben. Ein funktionierendes Mietgesetz ist somit aus sozialer und ökonomischer Sicht wichtig. Die Reform umfasst u.a. die Reduzierung der möglichen Mieterhöhungen seitens des Vermieters sowie eine Verkürzung der Kündigungsfrist seitens des Mieters. Die Ergebnisse zeigen, dass die Reform für die ersten Jahre eines Mietverhältnisses einen negativen Effekt auf die Miethöhe hat, der jedoch mit ansteigender Dauer des Mietverhältnisses verschwindet. Zudem finden sich stärkere Effekte bei hochpreisigen Mietwohnungen. Diese Dissertation liefert ein differenziertes Bild, wie die ökonomische Ungleichheit gemildert werden kann. Auf der einen Seite beschäftigt sich die Dissertation mit der Bildung von nichtkognitiven Kompetenzen, die hilfreich sind um insbesondere Geringqualifizierte in Beschäftigung und zu besser bezahlten Jobs zu bringen. Auf der anderen Seite wird der Effekt einer Mietrechtsreform evaluiert. Während ein förderlicher Effekt von strukturierten Aktivitäten auf die Bildung von charakterlichen Fähigkeiten festgestellt werden kann, zeigt sich bei der Evaluierung der Mietrechtsreform, dass geringverdienende Haushalte nicht im gleichen oder höheren Umfang von der Reform profitieren als finanziell besser gestellte Haushalte.']] | ['gnd:1050624300', 'gnd:4186884-5', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A864380739'] | ['Fuchs, Benjamin', 'Ungleichheit'] | 19 | 81,412 | Document

The second essay examines the effect of working part-time while attending full-time schooling on the development of character skills and occupational choice strategies. Comparing adolescents who hold a job with adolescents who do not work, the former spend less time in front of a screen and invest more time in academic learning. Focusing on the time use of employed adolescents, working part-time has an ambivalent effect on time invested in other activities. It reduces their homework time as well as their nonproductive screen time. The results imply that holding a paid job while still in school reduces the uncertainty about own interests and talents and reduces the dependency on parents. A third essay evaluates the impact of the Tenancy Law Reform Act in 2001, a policy which targets to protect especially low-income households against rent increase. Germany is one of the European countries with the highest percentage of the population who lives in tenancies. This illustrates the importance of a functioning tenancy law, socially and economically. This essay analyzes the effect of the reform on the level of rents as well as on the residency discount. The two substantial parts of the reform were the reduction of the maximum rent increases for sitting tenants and the reduction of the minimum notice period until termination of a tenancy by the tenant. Estimating the effect over the distribution of rents, the reform shows a significant negative effect on rents that is stronger at higher quantiles. The annual residency discount increases with the reform during the first three years of a tenancy and vanishes thereafter. The evidence suggests that the reform was successful in curtailing rent increases especially for expensive apartments early in a tenancy. This thesis provides a differentiated picture on how economic inequalities can be alleviated. On the one side, this thesis focuses on the formation of character skills which are helpful for bringing especially unskilled people into employment and to better paid jobs. On the other side, this thesis focuses on a tenancy law reform that targeted to protect tenants against rent increases. While beneficial effects of structured leisure activities on the formation of character skills can be detected, one may be concerned that the tenancy law reform may not have been sufficiently targeted if considering the target of the reform to protect especially low-income households against rent increases.', 'Diese Dissertation liefert ein differenziertes Bild zu zwei Interventionen und einer Politikreform um die ökonomische Ungleichheit zu mildern. In zwei Aufsätzen wird dabei auf die Rolle von außerschulischen Aktivitäten bei der Bildung von charakterlichen und sozialen Fähigkeiten eingegangen. Der erste Aufsatz in dieser Dissertation betrachtet den Einfluss einer regelmäßigen Ausübung von Sport auf die Entwicklung von charakterlichen und sozialen Fähigkeiten. Die Ergebnisse zeigen, dass Sport generell eine soziale Aktivität ist. Für Jugendliche aus sozial benachteiligten Schichten stellt Sport meistens die einzige qualitativ wertvolle Freizeitbeschäftigung dar. Sport hat einen förderlichen Einfluss auf ein breites Spektrum an Kompetenzen. Dieser Einfluss wird insbesondere durch Jugendliche, die keine anderen strukturierten Freizeitaktivitäten ausüben, getrieben. Zudem kann der Effekt von Sport als einen umfassenderen Einfluss des Zugangs zu einer bereichernden sozialen Umgebung interpretiert werden. Der zweite Aufsatz untersucht den Einfluss der Ausübung von Nebenjobs als Schüler auf die Entwicklung der Persönlichkeit und von Einstellungen und Strategien zur eigenen Berufswahl. Die Ergebnisse zeigen, dass Schüler, die neben der schulischen Ausbildung eine beruflichen Tätigkeit nachgehen, mehr Zeit in schulisches Lernen investieren und weniger Zeit vor einem Bildschirm verbringen. Jedoch verringert sich die Zeit die mit Hausaufgaben verbracht wird wie auch die nichtproduktive Zeit vor einem Bildschirm, wenn neben der Schule noch gejobbt wird. Insgesamt hat ein Nebenjob förderliche Effekte auf die eigene Unabhängigkeit gegenüber den Eltern und verringert die Unsicherheit über eigene Interessen und Fähigkeiten. Der dritte Aufsatz der Dissertation evaluiert den Einfluss der Mietrechtsreform in Deutschland im Jahr 2001. Diese Reform beabsichtigt u.a. geringverdienende Haushalte vor Mietanstiegen zu schützen. Im Vergleich zu anderen europäischen Staaten weist Deutschland den höchsten Anteilssatz an der Bevölkerung auf, die in Mietverhältnissen leben. Ein funktionierendes Mietgesetz ist somit aus sozialer und ökonomischer Sicht wichtig. Die Reform umfasst u.a. die Reduzierung der möglichen Mieterhöhungen seitens des Vermieters sowie eine Verkürzung der Kündigungsfrist seitens des Mieters. Die Ergebnisse zeigen, dass die Reform für die ersten Jahre eines Mietverhältnisses einen negativen Effekt auf die Miethöhe hat, der jedoch mit ansteigender Dauer des Mietverhältnisses verschwindet. Zudem finden sich stärkere Effekte bei hochpreisigen Mietwohnungen. Diese Dissertation liefert ein differenziertes Bild, wie die ökonomische Ungleichheit gemildert werden kann. Auf der einen Seite beschäftigt sich die Dissertation mit der Bildung von nichtkognitiven Kompetenzen, die hilfreich sind um insbesondere Geringqualifizierte in Beschäftigung und zu besser bezahlten Jobs zu bringen. Auf der anderen Seite wird der Effekt einer Mietrechtsreform evaluiert. Während ein förderlicher Effekt von strukturierten Aktivitäten auf die Bildung von charakterlichen Fähigkeiten festgestellt werden kann, zeigt sich bei der Evaluierung der Mietrechtsreform, dass geringverdienende Haushalte nicht im gleichen oder höheren Umfang von der Reform profitieren als finanziell besser gestellte Haushalte.']]

I study the time evolution of circumstellar nebula by analysing and comparing the two epochs of HST observations. Radial colour analysis of outer dust arc is done as well to check whether the radial grain size distribution was modified by a previous FUor wind. HST images are cleaned using IRAF and PSF subtraction is done using model PSF generated from Tiny Tim software. IDL scripts and routines are used to do proper motion analysis. The outer dust arc is found to be expanding at ≈ 14.8± 3.6 km s−1 on average. The expansion velocity of inner ring is less consistent, between 0.8 km s−1 and 3.4 km s−1. Radial colour profiles do not hint on particle separation. The results support the view that V1331 Cyg underwent an FU Orionis outburst a few thousand years ago. Additional data from other instruments - TLS, UKIDSS, SPITZER, HERSCHEL, SUBARU, PdBI and SMA is also incorporated.

### Title:
['Young star V1331 Cygni takes centre stage']
### Abstract:
['With first epoch observations of HST-WFPC2 already available for V1331 Cyg from year 2000, second epoch data was observed in 2009. I study the time evolution of circumstellar nebula by analysing and comparing the two epochs of HST observations. Radial colour analysis of outer dust arc is done as well to check whether the radial grain size distribution was modified by a previous FUor wind. HST images are cleaned using IRAF and PSF subtraction is done using model PSF generated from Tiny Tim software. IDL scripts and routines are used to do proper motion analysis. The outer dust arc is found to be expanding at ≈ 14.8± 3.6 km s−1 on average. The expansion velocity of inner ring is less consistent, between 0.8 km s−1 and 3.4 km s−1. Radial colour profiles do not hint on particle separation. The results support the view that V1331 Cyg underwent an FU Orionis outburst a few thousand years ago. Additional data from other instruments - TLS, UKIDSS, SPITZER, HERSCHEL, SUBARU, PdBI and SMA is also incorporated. I use it to improve the understanding of the young star in terms of environment, viewing angle, bipolar outflow length and missing ring section. The gap between the outer and inner dust arcs is found to be real. HST planetary camera image reveals a knot like feature at 220 au from the central source. Subaru image shows scattered light in the same direction as that of the knot. Preliminary results from the latest PdBI continuum map also hint on the knot being a real feature. It is evident from the knot photometry that it is not a binary stellar companion. The starlight scattered from the dust is seen in HST images. Missing ring section could be a result of shadowing due to presence of the knot. By viewing V1331 Cyg almost pole-on, the length of the bipolar outflow is updated to be 10 parsec or even more.']

In that sense, this thesis describes 3 studies which provide new knowledge of factors that influence processes mediated by soil microorganisms. This thesis focused in understanding 1) the mechanisms behind the plant diversity effect on the C transfer from above to belowground; 2) the influence of plant diversity on different soil microbial groups, soil bacterial diversity and phospholipid fatty acid (PLFA) markers evenness; and 3) the relative importance of the combined effects of soil type, seasonal changes and vegetation type. The results demonstrated that plant diversity impacted soil microbial communities directly and indirectly. Root-associated microorganisms were favored directly by plant diversity via increased root biomass, which facilitated access of recently photosynthesized C for this microbial group. In contrast, soil-related microorganisms were favored indirectly by plant diversity. Likely, increased C resource input contributed to the development of soil-related microbial biomass in high plant diversity. Moreover, soil bacterial diversity increased with increasing plant diversity, whilst PLFA evenness decreased. Interestingly, at the highest plant diversity level, PLFAs indicative of root-associated microorganisms predominated; this indicated that plant diversity favors the cycling of recently photosynthesized C.

### Title:
['Plant and soil related effects on the soil microbial community composition and soil microbial carbon dynamics']
### Abstract:
['Soil microorganisms are key mediators of soil carbon (C) cycling; however several plant and soil related factors potentially influence the functions of soil microbial communities. In that sense, this thesis describes 3 studies which provide new knowledge of factors that influence processes mediated by soil microorganisms. This thesis focused in understanding 1) the mechanisms behind the plant diversity effect on the C transfer from above to belowground; 2) the influence of plant diversity on different soil microbial groups, soil bacterial diversity and phospholipid fatty acid (PLFA) markers evenness; and 3) the relative importance of the combined effects of soil type, seasonal changes and vegetation type. The results demonstrated that plant diversity impacted soil microbial communities directly and indirectly. Root-associated microorganisms were favored directly by plant diversity via increased root biomass, which facilitated access of recently photosynthesized C for this microbial group. In contrast, soil-related microorganisms were favored indirectly by plant diversity. Likely, increased C resource input contributed to the development of soil-related microbial biomass in high plant diversity. Moreover, soil bacterial diversity increased with increasing plant diversity, whilst PLFA evenness decreased. Interestingly, at the highest plant diversity level, PLFAs indicative of root-associated microorganisms predominated; this indicated that plant diversity favors the cycling of recently photosynthesized C. In addition, changing root biomass in different soil types was an important mediator of C resource availability belowground. Whereas, differences in the type of C substrate, from fresh C rhizodeposits to plant litter, related to seasonal changes, were relevant for shaping the microbial community composition. Overall, this thesis contributes to strengthen the knowledge on the role of microbial communities in the C cycling belowground.']

Howmuch fiber is needed and how fibers should be distributed through a fiber reinforced composite (FRC) structure in order to obtain the optimal and reliable structural response? 2. How do uncertainties influence the optimization results and reliability of the structure? Giving answer to the above questions a double stage sequential optimization algorithm for finding the optimal content of short fiber reinforcements and their distribution in the composite structure, considering uncertain design parameters, is presented. In the first stage, the optimal amount of short fibers in a FRC structure with uniformly distributed fibers is conducted in the framework of a Reliability Based Design Optimization (RBDO) problem. Presented model considers material, structural and modeling uncertainties. In the second stage, the fiber distribution optimization (with the aim to further increase in structural reliability) is performed by defining a fiber distribution function through a Non-Uniform Rational BSpline (NURBS) surface. The advantages of using the NURBS surface as a fiber distribution function include: using the same data set for the optimization and analysis; high convergence rate due to the smoothness of the NURBS; mesh independency of the optimal layout; no need for any post processing technique and its non-heuristic nature. The output of stage 1 (the optimal fiber content for homogeneously distributed fibers) is considered as the input of stage 2. The output of stage 2 is the Reliability Index (b ) of the structure with the optimal fiber content and distribution. First order reliability method (in order to approximate the limit state function) as well as different material models including Rule of Mixtures, Mori-Tanaka, energy-based approach and stochastic multi-scales are implemented in different examples. The proposed combined model is able to capture the role of available uncertainties in FRC structures through a computationally efficient algorithm using all sequential, NURBS and sensitivity based techniques. The methodology is successfully implemented for interfacial shear stress optimization in sandwich beams and also for optimization of the internal cooling channels in a ceramic matrix composite. Finally, after some changes and modifications by combining Isogeometric Analysis, level set and point wise density mapping techniques, the computational framework is extended for topology optimization of piezoelectric / flexoelectric materials.'] | ['gnd:1120622646', 'gnd:135943620', 'gnd:4017233-8', 'gnd:4043664-0', 'gnd:4134341-4', 'gnd:5180842-0', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A873191625'] | ['Rabczuk, Timon', 'Lahmer, Tom', 'Finite-Elemente-Methode', 'Optimierung', 'Faserverbundwerkstoff', 'Bauhaus-Universität Weimar'] | 27 | 81,475 | Document

Howmuch fiber is needed and how fibers should be distributed through a fiber reinforced composite (FRC) structure in order to obtain the optimal and reliable structural response? 2. How do uncertainties influence the optimization results and reliability of the structure? Giving answer to the above questions a double stage sequential optimization algorithm for finding the optimal content of short fiber reinforcements and their distribution in the composite structure, considering uncertain design parameters, is presented. In the first stage, the optimal amount of short fibers in a FRC structure with uniformly distributed fibers is conducted in the framework of a Reliability Based Design Optimization (RBDO) problem. Presented model considers material, structural and modeling uncertainties. In the second stage, the fiber distribution optimization (with the aim to further increase in structural reliability) is performed by defining a fiber distribution function through a Non-Uniform Rational BSpline (NURBS) surface. The advantages of using the NURBS surface as a fiber distribution function include: using the same data set for the optimization and analysis; high convergence rate due to the smoothness of the NURBS; mesh independency of the optimal layout; no need for any post processing technique and its non-heuristic nature. The output of stage 1 (the optimal fiber content for homogeneously distributed fibers) is considered as the input of stage 2. The output of stage 2 is the Reliability Index (b ) of the structure with the optimal fiber content and distribution. First order reliability method (in order to approximate the limit state function) as well as different material models including Rule of Mixtures, Mori-Tanaka, energy-based approach and stochastic multi-scales are implemented in different examples. The proposed combined model is able to capture the role of available uncertainties in FRC structures through a computationally efficient algorithm using all sequential, NURBS and sensitivity based techniques. The methodology is successfully implemented for interfacial shear stress optimization in sandwich beams and also for optimization of the internal cooling channels in a ceramic matrix composite. Finally, after some changes and modifications by combining Isogeometric Analysis, level set and point wise density mapping techniques, the computational framework is extended for topology optimization of piezoelectric / flexoelectric materials.']

The main feature of this process, compared with other technologies, is that the coatings are deposited in solid state phase. Therefore, the induced massive deformation alters the initial microstructure of the materials, resulting in a fully recrystallised microstructure of the coatings. Typically, the grain size of the coating is smaller than that of the raw material, which leads to improved mechanical properties. Since the process is a relatively new technology, several possible material combinations in similar or dissimilar configurations are unexplored. Titanium alloys are rather expensive. Therefore, new technologies are required to keep the production cost at an acceptable level and offer an additional cladding process that is environmental friendly. The aim of the current work was to deposit coatings from the titanium alloys by friction surfacing. Process development for Ti-6Al-4V alloy and Ti-Gr.1 as coating materials to be deposited by friction surfacing was carried out. At high temperatures titanium alloys exhibit complex deformation behaviour, particularly when passing through the alpha-beta phase transformation and in the beta phase state.

A broad range of parameter sets for titanium depositions has been established, whereby two different acting rotational speed regimes were observed. The low rotational speed regime revealed variations in the process temperature, which influenced the material flow behaviour leading to flash generation at the coating. The microstructure in this regime consists of refined dynamically recrystallised grains. In contrast, the high rotational speed regime revealed a higher resulting temperature, which did not vary in this range. This constant temperature led to stable material flow behaviour and flash-free coatings were deposited. However, the high temperature influenced the grain size of the coatings resulting in coarse grains. Still, these differences in the grain size did not influence the fretting wear behaviour of the coatings. The investigation of fretting wear experiments exposed a similar behaviour of friction surfacing coatings and the base material. In micro tensile tests the coatings exhibited an increase in strength but a decrease in ductility, which is typical for dynamically recrystallised materials, which contain residual deformation. Therefore, it could be shown that friction surfacing can be considered as a repair method for titanium parts.', 'Das Reibauftragschweißverfahren ist eine relativ neue und vielversprechende Technologie zur Oberflächenmodifikation technischer Komponenten. Hierbei können Beschichtungen zur lokalen Eigenschaftsänderung oder zu Reparaturzwecken erzeugt werden. Das Hauptmerkmal dieses Verfahrens, im Vergleich zu konventionellen Beschichtungsmethoden, ist, dass die Schichten in der Festphase aufgetragen werden. Durch die eingebrachte massive plastische Verformung des Werkstoffes ändert sich die Mikrostruktur und es entsteht ein vollständig rekristallisiertes Gefüge. Die Korngröße der entstandenen Schichten ist im Regelfall kleiner als die des Ausgangsmaterials, was zu verbesserten mechanischen Eigenschaften führt. Weil das Reibauftragschweißen ein relativ neues Verfahren ist, sind einige der möglichen Materialkombinationen in artgleichen und artfremden Paarungen noch unerforscht. Aufgrund dessen, dass Titanlegierungen als Ausgangswerkstoff kostspielig sind, sind neue Technologien, welche die Produktionskosten reduzieren können, von großem Interesse. Mit dem Reibauftragschweißen bietet sich ein Beschichtungsverfahren an, welches auch modernen Ansprüchen an die Umweltverträglichkeit gerecht wird. Das Ziel der vorliegenden Arbeit war es, Schichten aus Titanlegierungen mittels Reibauftragschweißen aufzutragen. Dafür wurde die Prozessentwicklung für die Werkstoffe Ti-6Al-4V und Ti-Gr.1 realisiert. Titanlegierungen weisen ein komplexes Umformverhalten bei hohen Temperaturen auf, insbesondere, wenn sie sowohl den alpha-beta-, als auch den beta-Phasenbereich beim Umformen durchlaufen. Hierbei sind Dehnratenempfindlichkeit und Fließinstabilität charakteristisch für Titanlegierungen, was die Verarbeitung beim Reibauftragschweißen erschweren kann. Diese Schwierigkeiten wurden durch die systematische Erarbeitung geeigneter Prozessparameter und einer zielführenden Prozesssteuerung überwunden. Es wurde ein breites Parameterfenster etabliert, innerhalb dessen zwei verschiedene Regimes der Drehzahlen gefunden wurden, zwischen denen sich das Materialverhalten deutlich unterscheidet. Das niedrige Drehzahl-Regime weist dabei Veränderungen in der Prozesstemperatur auf, welche die Fließeigenschaften des Werkstoffs beeinflussen, was wiederum zu einer Wulstbildung an den Schichten führt. Die Mikrostruktur in diesem Regime offenbart feine, dynamisch rekristallisierte Körner. Dazu gegensätzlich weist das hohe Drehzahl-Regime eine höhere resultierende Temperatur auf, die in diesem Bereich nicht variiert. Die konstante Temperatur führt zu einem stabilen Materialfließverhalten und ermöglicht damit eine dementsprechend wulstfreie Realisierung von Schichten. Allerdings führen diese hohen Temperaturen zu einem Anstieg in der Korngröße. Die in Bezug auf die Korngröße unterschiedlich entwickelte Mikrostruktur zeigte keinen Einfluss auf das Schwingungsverschleißverhalten der Schichten. Die Verschleißeigenschaften der Schichten und des Grundwerkstoffs erwiesen sich als vergleichbar. Im Zuge von Mikroflachzug-Tests offenbarten die Schichten eine erhöhte Festigkeit mit leichten Einbußen in der Duktilität, was ein charakteristisches Verhalten für dynamisch rekristallisierte Werkstoffe bei Vorhandensein von Restverformung ist. Somit konnte gezeigt werden, dass das Reibauftragschweißen als Reparaturmethode für Titan- Bauteile, grundsätzlich in Betracht gezogen werden kann.']] | ['gnd:10184290-9', 'gnd:1133309526', 'gnd:2067664-5', 'gnd:4053870-9', 'gnd:4185562-0', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A875851010'] | ['Technische Universität Hamburg-Harburg, Institut für Werkstoffphysik und -technologie', 'Huber, Norbert', 'Technische Universität Hamburg-Harburg', 'Schweißen', 'Titanlegierung'] | 15 | 81,494 | Document

Still, these differences in the grain size did not influence the fretting wear behaviour of the coatings. The investigation of fretting wear experiments exposed a similar behaviour of friction surfacing coatings and the base material. In micro tensile tests the coatings exhibited an increase in strength but a decrease in ductility, which is typical for dynamically recrystallised materials, which contain residual deformation. Therefore, it could be shown that friction surfacing can be considered as a repair method for titanium parts.', 'Das Reibauftragschweißverfahren ist eine relativ neue und vielversprechende Technologie zur Oberflächenmodifikation technischer Komponenten. Hierbei können Beschichtungen zur lokalen Eigenschaftsänderung oder zu Reparaturzwecken erzeugt werden. Das Hauptmerkmal dieses Verfahrens, im Vergleich zu konventionellen Beschichtungsmethoden, ist, dass die Schichten in der Festphase aufgetragen werden. Durch die eingebrachte massive plastische Verformung des Werkstoffes ändert sich die Mikrostruktur und es entsteht ein vollständig rekristallisiertes Gefüge. Die Korngröße der entstandenen Schichten ist im Regelfall kleiner als die des Ausgangsmaterials, was zu verbesserten mechanischen Eigenschaften führt. Weil das Reibauftragschweißen ein relativ neues Verfahren ist, sind einige der möglichen Materialkombinationen in artgleichen und artfremden Paarungen noch unerforscht. Aufgrund dessen, dass Titanlegierungen als Ausgangswerkstoff kostspielig sind, sind neue Technologien, welche die Produktionskosten reduzieren können, von großem Interesse. Mit dem Reibauftragschweißen bietet sich ein Beschichtungsverfahren an, welches auch modernen Ansprüchen an die Umweltverträglichkeit gerecht wird. Das Ziel der vorliegenden Arbeit war es, Schichten aus Titanlegierungen mittels Reibauftragschweißen aufzutragen. Dafür wurde die Prozessentwicklung für die Werkstoffe Ti-6Al-4V und Ti-Gr.1 realisiert. Titanlegierungen weisen ein komplexes Umformverhalten bei hohen Temperaturen auf, insbesondere, wenn sie sowohl den alpha-beta-, als auch den beta-Phasenbereich beim Umformen durchlaufen. Hierbei sind Dehnratenempfindlichkeit und Fließinstabilität charakteristisch für Titanlegierungen, was die Verarbeitung beim Reibauftragschweißen erschweren kann. Diese Schwierigkeiten wurden durch die systematische Erarbeitung geeigneter Prozessparameter und einer zielführenden Prozesssteuerung überwunden. Es wurde ein breites Parameterfenster etabliert, innerhalb dessen zwei verschiedene Regimes der Drehzahlen gefunden wurden, zwischen denen sich das Materialverhalten deutlich unterscheidet. Das niedrige Drehzahl-Regime weist dabei Veränderungen in der Prozesstemperatur auf, welche die Fließeigenschaften des Werkstoffs beeinflussen, was wiederum zu einer Wulstbildung an den Schichten führt. Die Mikrostruktur in diesem Regime offenbart feine, dynamisch rekristallisierte Körner. Dazu gegensätzlich weist das hohe Drehzahl-Regime eine höhere resultierende Temperatur auf, die in diesem Bereich nicht variiert. Die konstante Temperatur führt zu einem stabilen Materialfließverhalten und ermöglicht damit eine dementsprechend wulstfreie Realisierung von Schichten. Allerdings führen diese hohen Temperaturen zu einem Anstieg in der Korngröße. Die in Bezug auf die Korngröße unterschiedlich entwickelte Mikrostruktur zeigte keinen Einfluss auf das Schwingungsverschleißverhalten der Schichten. Die Verschleißeigenschaften der Schichten und des Grundwerkstoffs erwiesen sich als vergleichbar. Im Zuge von Mikroflachzug-Tests offenbarten die Schichten eine erhöhte Festigkeit mit leichten Einbußen in der Duktilität, was ein charakteristisches Verhalten für dynamisch rekristallisierte Werkstoffe bei Vorhandensein von Restverformung ist. Somit konnte gezeigt werden, dass das Reibauftragschweißen als Reparaturmethode für Titan- Bauteile, grundsätzlich in Betracht gezogen werden kann.']]
