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

Thermodynamic description is presented for the ternary Cu–Fe–Mn system at its Cu–Fe side. The thermodynamic parameters of the sub-systems, Cu–Fe, Cu–Mn and Fe–Mn, 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 40 wt%.
