Thermodynamic investigation of the galvanizing systems, II: Thermodynamic evaluation of the Ni–Zn system

The Ni–Zn system is reassessed using the CALPHAD approach. An order–disorder transition model is adopted to describe the intermetallic phase with an ordered bcc_B2 structure. A set of self-consistent thermodynamic parameters of the Ni–Zn system is obtained based on the available experimental information. The present modeling shows good agreement with the experimental data and predicts the thermodynamic properties of the Ni–Zn alloys reasonably, which indicates the importance of the CALPHAD technique to study galvanizing systems. The present thermodynamic description of the Ni–Zn system is in the framework for constructing a comprehensive thermodynamic database to design the process of galvanizing.
