Thermodynamic description of the Cu–Ni–Zn system above 600 ∘C

Thermodynamic description of the ternary Cu–Ni–Zn system is presented. The thermodynamic parameters of the binary sub-systems, Cu–Ni, Cu–Zn and Ni–Zn, are taken from earlier SGTE-based assessments (modifying the Ni–Zn description slightly) and those of the ternary Cu–Ni–Zn system are optimized in this study by using the experimental thermodynamic and phase equilibrium data. The present ternary description is valid at zinc contents up to 70 wt% and at temperatures above 600 ∘C .
