2017年博士学术论坛第13期:Towards an atomistic understanding of the deformation mechanisms of metallic glasses

发布时间:2017年11月28日    点击数:563

报告题目:

Towards an atomistic understanding of the deformation mechanisms

of metallic glasses

报告内容:

By using large-scale molecular dynamics simulations, the report will provide an atomistic understanding of the deformation mechanisms of metallic glass nanowires and differentiate the extrinsic size effects and aspect ratio contribution to plasticity. Bulk metallic glass composites (BMGC) reinforced with a crystalline phase, which shows stress-induced martensitic transformation exhibit both enhanced ductility and work hardening as compared to the conventional BMGC. Here, the report will investigate the deformation mechanism of CuZr BMGC with B2 inclusions and glass-crystalline nanolaminates and provide an effective strategy to control the strain localization in these nanostructures by systematically varying the fraction of the martensitic phase and its spatial distribution.
