1984年后在密度函数理论基础上发展起来的嵌入原子方法(EAM)理论,在合金相理论中有着广泛的用途.1989年Johnson运用他所提出的EAM理论方法计算了过渡族FCC金属二元合金的稀溶解热和形成热,结果与实验数据及第一原理计算结果符合较好.但至今尚未见EAM理论对BCC金属二元合金热力学性质计算报道.我们使用1990年Johnson提出的BCC金属EAM模型的原有形式进行了计算,发现结果较差,与实验 The theory of embedded atoms (EAM) developed on the basis of the theory of density function after 1984 has been widely used in the theory of alloy phase. In 1989, Johnson calculated the transition state FCC metal binary alloy by using the EAM theory proposed by him Dilute solution heat and formation of heat, and the results are in good agreement with the experimental data and the first principle calculation. However, no calculation of the thermodynamic properties of BCC metal binary alloys has been reported by EAM so far.We used the BCC metal EAM model proposed by Johnson in 1990 The original form was calculated and found to be poor and experimental
