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.
