采用分子动力学方法模拟了Ph20Auso和Pb50Au50合金体系的热力学性质,计算了不同温度下合金体系的生成焓、生成自由能、过剩自由能和结合能,从宏观和微观热力学角度分析了二元合金原子间的相互作用,得到的计算结果与实验数据很吻合。
Molecular Dynamics method is used to simulate the thermodynamic properties of two binary alloys: Pb20Au50 ,Pb50Au50. Enthalpy of formation, free energy of formation, excess free energy and cohesive energy of two alloys have been calculated. The atomic interactions have been analyzed in macroscopic and microcosmic view. The values obtained here are consistent well with those of the experiments.
