Thermodynamic description of the CuAlFe system at the CuFe side

Thermodynamic description of the ternary CuAlFe system at the CuFe side is presented. The thermodynamic parameters of the sub-systems, CuAl, CuFe and AlFe, are taken from earlier SGTE-based assessments, and those of the ternary CuAlFe system are optimized in this study by using the experimental phase equilibrium data. The present ternary description is valid for aluminum contents up to 18 wt%.
