Thermodynamic description of the Cu–Mn–Ni system at the Cu–Ni side

Abstract

Thermodynamic description of the ternary Cu–Mn–Ni system at its Cu–Ni side is presented. The thermodynamic parameters of the sub-systems, Cu–Mn, Cu–Ni and Mn–Ni, are taken from earlier SGTE-based assessments and those of the ternary Cu–Mn–Ni system are optimized in this study by using the experimental phase equilibrium data. The present ternary description is valid for manganese contents up to 70 wt%.
