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

Thermodynamic description of the ternary Cu–Fe–Si system at the Cu–Fe side is presented. The thermodynamic parameters of the sub-systems, Cu–Fe, Cu–Si and Fe–Si, are taken from earlier SGTE-based assessments (modifying slightly the bcc description of the Fe–Si system), and those of the ternary Cu–Fe–Si system are optimized in this study by using the experimental phase equilibrium data. The present ternary description is valid for silicon contents up to 10 wt%.
