Abstract: By means of constant temperature and constant pressure molecular dynamic simulation technique, a series of simulations of the glass transition and crystallization processes of Ag₅₀Au₅₀ were performed. The atoms interact via EAM potential function. Pair correlation functions of liquid Ag₅₀Au₅₀ during different cooling rates and temperatures were simulated to reveal the structural features of liquid, super-cooled liquid, glass state and crystal. The thermodynamics and kinetics of structure transition of Ag₅₀Au₅₀ during cooling processes were performed.
