Abstract

We performed molecular-dynamics simulation and predicted a strong coupling between chemical short-range order and dynamic heterogeneity in a multicomponent Cu45 Zr45 Ag10 alloy that possesses excellent glass-forming ability. The intrinsic correlation between the chemical and dynamic heterogeneities leads to significant spatial partitioning and dynamic isolation between Cu-rich slow-dynamics regions and Ag-rich fast-dynamics regions. This characteristic may play an important role in the improved glass-forming ability with Ag addition by retarding crystallization kinetics.
