Although the atomic structure of amorphous alloys, which lacks long-range translational
symmetry, may appear homogeneous at the macroscopic scale, their local dynamic and/or …

Hardness and fracture toughness are some of the most important mechanical properties.
Here, we propose a simple model that uses only the elastic properties to calculate the …

In a crystalline material, structural defects such as dislocations or twins are well defined and
largely determine the mechanical and other properties of the material. For metallic glass …

Understanding the fracture toughness of glasses is of prime importance for science and
technology. We study it here using extensive atomistic simulations in which the interaction …

It is shown that all heat effects taking place upon annealing of a metallic glass within the
glassy and supercooled liquid states, ie heat release below the glass transition temperature …

It is widely known that crystallization of metallic glasses is accompanied by a strong heat
release. Current literature considers this phenomenon in a general sense as a result of …

非晶合金是一类具有诸多优异性能的先进金属材料, 同时也是研究非晶态物质的模型体系. 最近,
