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

Thermodynamic description is presented for the ternary Cu–Mn–Si system in its copper-rich corner. The thermodynamic parameters of the sub-systems, Cu–Mn, Cu–Si and Mn–Si, are taken from earlier SGTE-based assessments and those of the ternary system are optimized in this study by using the experimental phase equilibrium data. The present ternary description is valid for manganese contents up to 30 wt% and silicon contents up to 10 wt%.
