| 摘 要： | 分析了Miedema理论,在二元合金热力学性质计算时,用Miedema理论结合几何模型的方法,能为生产实验提供理论依据。对于多元合金体系热力学性质的计算,由二元系溶体的热力学性质推算多元合金体系热力学性质的溶体模型,并介绍了由Toop模型和周模型外推得到的Miedema模型。但对于多元合金体系,其理论值与实验值并不如二元合金体系符合得那样好,为了能精确地计算三元以及多元合金体系的热力学性质,还需要对几何模型作进一步完善.

| Abstract: | The Miedema model,which has been used widely for calculating thermodynamic properties of binary alloys system,is introduced.Using Miedema theory along with geometrical model method in the calculation of thermodynamic properties of binary alloys can provide theoretical basis for production experiment.An extended Miedema model for calculating thermodynamic properties of multi-component system,which is extended by Toop and Zhou models,is reviewed.It is suggested that the reforming and development of geometrica... |
