10. On the correlation of shear band formation and texture evolution in $\alpha$-brass during accumulative roll bonding

Abstract

We studied the microstructural evolution of the low stacking fault energy $\alpha$-brass alloy CuZn15 during accumulative roll bonding (ARB). Most notably, the typical brass-type texture was clearly observed after four ARB passes (approx. 93.8 % total thickness reduction), before significant shear localization set in. This observation contradicts the widely accepted idea that shear band formation is a necessary prerequisite for the development of the brass type texture, indicating that the two phenomena, shear banding and development of the brass texture, are only correlated in ARB, and that their order of appearance can be switched depending on experimental parameters., Comment: 4 pages, 2 figures

15. Growth, microstructure and thermal transformation behaviour of epitaxial Ni-Ti films

Abstract

Epitaxial films have the potential to be used as model systems for fundamental investigations on the martensitic transformation in binary NiTi. In this paper, we discuss growth of binary NiTi thin films on single crystalline MgO substrates. Sputter deposition is used to grow NiTi films. Films prepared by complementary preparation routes (with different deposition temperatures and subsequent heat treatments) are investigated by X-ray diffraction, electron microscopy, atomic force microscopy, and electrical resistivity measurements, with the aim of optimizing film properties, particularly to obtain a well defined orientation of the austenitic unit cell and smooth surfaces. Our results show that deposition at elevated temperatures and carefully controlled subsequent heat treatments allow to produce epitaxially grown and smooth NiTi films that exhibit reversible one- or two-step martensitic transformations., Comment: 9 figures

29. Scientific and Engineering Progress on Aluminum-Based Light-Weight Materials : Research Reports from the German Collaborative Research Center 692

Author

Wagner, Martin F. X.

Abstract

Aluminum-based light-weight materials offer great potential for novel engineering applications, particularly when they are optimized to exhibit high strength and yet provide sufficient reliability. The last decade has thus seen substantial activity in the research fields of high-strength aluminum alloys and aluminum-based composite materials.For twelve years, backed by solid funding from the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG), scientists of the Collaborative Research Center, “High-strength aluminum-based light-weight materials for safety components” (SFB 692) at TU Chemnitz, Germany, have contributed to this research area. Our research efforts have been focused on three main areas: ultrafine-grained aluminum alloys produced by severe plastic deformation; aluminum matrix composites; and aluminum-based composite materials (including material combinations such as magnesium/aluminum or steel/aluminum and the corresponding joining and forming technologies). The framework of SFB 692 has served as a base for numerous scientific collaborations between scientists in the fields of materials science, design engineering, production engineering, mechanics, and even economics—in Chemnitz, and with many well-established international experts around the world.In this Special Issue, we present recent results on high-strength aluminum-based light-weight materials that also provide a broad overview of research activities in SFB 692 and elsewhere.
