Abstract
Nano-sized powder composed of single crystals of an Au-13 at.%Pd alloy was produced by inert gas condensation (IGC). Uniaxial compaction of the powder was applied in two stages: already within the IGC chamber at 2 GPa pressure, followed by another compaction stage at 6 GPa, outside the chamber. This processing resulted in a weak 〈110〉 fiber texture of the compressed alloy. The crystallographic texture formation during compaction was simulated using different polycrystal plasticity models. The experimental texture evolution was faithfully reproduced using the relaxed constraints polycrystal plasticity model complemented with a grain boundary sliding approach.
期刊介绍：
Materials Characterization features original articles and state-of-the-art reviews on theoretical and practical aspects of the structure and behaviour of materials.
The Journal focuses on all characterization techniques, including all forms of microscopy (light, electron, acoustic, etc.,) and analysis (especially microanalysis and surface analytical techniques). Developments in both this wide range of techniques and their application to the quantification of the microstructure of materials are essential facets of the Journal.
The Journal provides the Materials Scientist/Engineer with up-to-date information on many types of materials with an underlying theme of explaining the behavior of materials using novel approaches. Materials covered by the journal include:
Metals & Alloys
Ceramics
Nanomaterials
Biomedical materials
Optical materials
Composites
Natural Materials.
