| 中文摘要 | Molecular dynamics simulations are performed for CuZr metallic alloys to study the structural and dynamical features for glass forming ability (GFA). Our analysis shows that in CuZr metallic system, although << 0,0,12,0 >> icosahedral clusters are important, some Zr-centered clusters such as << 0,1,10,4 >> and << 0,1,10,5 >> play a key role in slowing down the dynamics. It is found that these Zr-centered clusters are intrinsically slow and fundamentally determine the stability and slow dynamics. Due to the strong spatial correlation between << 0,0,12,0 >> and Zr-centered clusters, their relative population influences the dense packing and dynamics in metallic glasses, and further the GFA. |
