چکیده انگلیسی
The compressive mechanical properties at different strain rates were analysed in Zr85Cu15 nanocrystal-metallic glass composites by molecular dynamics simulations. Results showed that, with the increasing strain rate, more shear transformation zones appeared simultaneously in the composites. The evolution and the homogeneity of the shear transformation zones of the composites were also studied and it was found that, at a low strain rate (5 Ã 107 sâ 1), the plasticity of Zr85Cu15 metallic glasses was higher than that of Zr85Cu15 metallic glasses containing nanocrystalline components. However, at a high strain rate (109 sâ 1), the deformation of the nanocrystal-metallic glass composites was more homogenous and their mechanical properties were better than those of other metallic glasses.
