摘 要: 优化和计算了Ni-Zr 二元相图。液相用缔合物模型、端际固溶体用替换溶液模型描述,Ni5Zr 和 Ni10Zr7 则分别选用了(Ni)1(Ni, Va)4(Ni,Zr)1 和 (Ni,Zr)10Zr7 的亚点阵模型。计算结果与大部分相图和热力学数据相吻合。

Abstract:Optimization and calculation of the phase diagram of Ni-Zr binary system were presented. Associate model and substitute solution model were used to describe liguid and teminal solution phases respec-
tively. As to the intermediate compounds Ni5Zr and Ni10Zr7, sublattice model (Ni)1( Ni,Va)4(Ni,Zr)1 and (Ni, Zr)10Zr7 were selected. Both calculated phase diagram and thermodynamic properties agree well with most of relative experimental data.

 

Key words: associate model      substitute solution model     sublattice model
