Molecular dynamics calculation of the reduced glass transition temperature for a copper-silver metallic glass


A molecular dynamics simulation with an embedded atom method (EAM) potential was performed to simulate metallic glass formation in a 32000-atom cubic supercell of a Cu64 Ag36 alloy. The obtained cooling curve and pair distribution function possess features that support the formation of a metallic glass. The reduced glass transition temperature Trg was calculated to be 0.53, which passes the Turnbull criterion for good metallic glass formers.
