SIMULATION OF CRYSTALLIZATION AND GLASS FORMATION PROCESSES FOR BINARY Pd-Ag METAL ALLOYS

摘要

Glass formation and crystallization process of Pd-Ag metallic alloys are investigated by means of molecular dynamics simulation. This simulation uses the quantum Sutton-Chen (Q-SC) potential to study structural and transport properties of Pd-Ag alloys. Cooling rates and concentration effects on the glass formation and crystallization of binary alloys considered in this work are investigated. Pd-Ag alloys show the glass structure at fast cooling rates while it crystallizes at slow cooling rates. Increment of concentration of Ag in Pd-Ag alloys gives rise to glass structure at cooling rate 0.5 K/ps.
