Molecular dynamics study of the binaryCu46Zr54metallic glass motivated by experiments: Glass formation and atomic-level structure

Abstract

We have identified a binary bulk metallic glass forming alloy ${\mathrm{Cu}}_{46}{\mathrm{Zr}}_{54}$ by analyzing the structure and thermal behaviors of copper mold cast samples using x-ray diffraction, transmission electron microscopy, and differential scanning calorimeter. Motivated by these experimental results, we fitted the effective Rosato-Guillope-Legrand-type force field parameters for the binary Cu-Zr alloy system and the atomistic description of glass formation and structure analysis of the ${\mathrm{Cu}}_{46}{\mathrm{Zr}}_{54}$ alloy based on molecular dynamics simulation will be also presented.
