摘要: Abstract The structure and thermodynamics of liquid Au–Cu Au–Ag alloys have been simulated using molecular dynamics method based upon the EAM interatomic potential to reveal influence mismatch in atomic size on glass-forming ability. Under cooling rate range 4×10 12 1×10 11 K/s, system undergoes liquid, super-cooled solid state. Liquid Au always form crystal, higher rate, lower crystallization temperature; while forms a glass, glass transition temperature. is favorable formation glass.
