Thermodynamic description of the Cu–Mn–Zn system in the copper-rich corner

Thermodynamic description is presented for the ternary Cu–Mn–Zn system in its copper-rich corner. The thermodynamic parameters of the binary sub-systems, Cu–Mn and Cu–Zn, are taken from the earlier SGTE-based assessments, and those of the Mn–Zn and Cu–Mn–Zn systems are optimized in this study using the experimental phase equilibrium and thermodynamic data. The present ternary description is valid for manganese contents up to 30 wt% and zinc contents up to 60 wt%.
