摘要: 用修正的分析型嵌入原子方法计算了PdAu二元合金系的稀溶解热、形成焓、表面能和表面聚集能,并将计算的热力学性质与实验结果或第一性原理计算结果进行了比较.

关键词: 嵌入原子方法, 稀溶解热, 形成焓, 表面能, 表面聚集能

Abstract: An analytic modified embedded-atom model is presented.Using the model,the thermodynamic data,such as the dilute-limit heats of solution,formation enthalpies of disordered solid solutions,surface energies and surface segregation energies for Pd-Au alloy,are calculated.The results are in agreement with the experimental data and calculated data using ab initio theory.

Key words: embedded-atom method, dilute-limit heats of solution, formation enthalpies, surface energy and surface segregation energy
