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.
