Displacive processes in systems with bcc parent lattice [作者：Paidar, V,期刊：PROGRESS IN MATERIALS SCIENCE, 页码：841-851 , 文章类型： Article; Proceedings Paper，,卷期：2011年56-6] The changes of sample shape are caused by plastic deformation or by martensitic phase transformations. In both cases the mechanisms of atomic rearrangements are based on collective displacements of atomic aggregates. The... From non-planar dislocation cores to non-associated plasticity and strain bursts [作者：Bassani, JL; Racherla, V,期刊：PROGRESS IN MATERIALS SCIENCE, 页码：852-863 , 文章类型： Article; Proceedings Paper，,卷期：2011年56-6] In non-close-packed crystalline lattices, e.g. of bcc metals and inter-metallic compounds, the stress-state dependence of the Peierls barrier for the motion of a screw dislocation violates Schmid's law and leads to non-a... Topological and atomic scale characterization of grain boundary networks in polycrystalline and nanocrystalline materials [作者：Li, M; Xu, T,期刊：PROGRESS IN MATERIALS SCIENCE, 页码：864-899 , 文章类型： Article; Proceedings Paper，,卷期：2011年56-6] Microstructure in polycrystalline materials, either coarse-grained or nano-crystalline, is characterized by the topological structure of grain boundary networks which are composed of an array of complex geometric entitie... A Breakthrough Is Something You Don't See Coming Preface [作者：De Hosson, JTM,期刊：PROGRESS IN MATERIALS SCIENCE, 页码：573-576 , 文章类型： Editorial Material，,卷期：2011年56-6] Atomic level computer modelling of crystal defects with emphasis on dislocations: Past, present and future [作者：Vitek, V,期刊：PROGRESS IN MATERIALS SCIENCE, 页码：577-585 , 文章类型： Article; Proceedings Paper，,卷期：2011年56-6] Computer modelling is at present as important method of the study of materials and their properties as experiments. Yet, experiments have been being performed for several thousands years while computer modelling started ... Compatibility and accommodation in displacive phase transformations [作者：Hirth, JP; Pond, RC,期刊：PROGRESS IN MATERIALS SCIENCE, 页码：586-636 , 文章类型： Article; Proceedings Paper，,卷期：2011年56-6] The role of disconnections and lattice-invariant deformation in displacive phase transformations is reviewed, particularly the defect structure of equilibrium habit planes, the mechanism of transformation, and the deform... Atomic level stresses [作者：Egami, T,期刊：PROGRESS IN MATERIALS SCIENCE, 页码：637-653 , 文章类型： Article; Proceedings Paper，,卷期：2011年56-6] The birth and subsequent development of the concept of the atomic level stresses are reviewed, and its future is discussed. Initially it was conceived as a means of describing the local structure in metallic glasses. It ... Plasticity in small-sized metallic systems: Intrinsic versus extrinsic size effect [作者：Greer, JR; De Hosson, JTM,期刊：PROGRESS IN MATERIALS SCIENCE, 页码：654-724 , 文章类型： Article; Proceedings Paper，,卷期：2011年56-6] A material strength depends on its microstructure, which in turn, is controlled by an engineering process. Strengthening mechanisms like work hardening, precipitate, and grain boundary strengthening can alter the strengt... Scaling laws for dislocation microstructures in monotonic and cyclic deformation of fcc metals [作者：Sauzay, M; Kubin, LP,期刊：PROGRESS IN MATERIALS SCIENCE, 页码：725-784 , 文章类型： Article; Proceedings Paper，,卷期：2011年56-6] This work reviews and critically discusses the current understanding of two scaling laws, which are ubiquitous in the modeling of monotonic plastic deformation in face-centered cubic metals. A compilation of the availabl... Atomistic simulation and modeling of localized shear deformation in metallic glasses [作者：Takeuchi, S; Edagawa, K,期刊：PROGRESS IN MATERIALS SCIENCE, 页码：785-816 , 文章类型： Article; Proceedings Paper，,卷期：2011年56-6] Since the end of 1980s, bulk metallic glasses became available for various multi-component alloys. Because bulk metallic glasses are applicable to structural materials, their mechanical properties have become a matter of...
