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

A thermodynamic description is presented for the ternary Cu–Mn–Sn system in its copper-rich corner. The thermodynamic parameters of the binary sub-systems, Cu–Mn, Cu–Sn and Mn–Sn, are taken from the earlier SGTE-based assessments and those of the ternary Cu–Mn–Sn system are optimized in this study using experimental phase equilibrium data. The present ternary description is valid for manganese up to 30 wt% and tin contents up to 35 wt%.
