Abstract

The thermodynamic assessments of the Cu-Mn binary, Cu-Mn-Fe and Cu-Mn-Co ternary systems were carried out by using CALPHAD (calculation of phase diagrams) method on the basis of the experimental data including the thermodynamic properties and phase equilibria. The Gibbs free energies of the liquid, bcc, fcc, hcp, (αMn) and (βMn) phases are described by the subregular solution model. The thermodynamic parameters of the Cu-Mn binary, Cu-Mn-Fe and Cu-Mn-Co ternary systems have been optimized for reproducing the experimental results in each system, respectively. An agreement between the calculated results and experimental data is obtained.
