The Gibbs free energies of the liquid, bcc, fcc, hep, (alpha Mn) and (beta Mn) 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. (C) 2006 Published by Elsevier B.V
