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
