根据热力学性质和相平衡实验数据，用相图计算方法对Cu-Mn二元系、Cu-Mn-Fe系和Cu-Mn-Co系进行了热力学计算。用亚规则溶液模型描述了液相、bcc、fcc、hcp、（αMn）和（βMn）相的吉布斯自由能。对Cu-Mn二元系、Cu-Mn-Fe系和Cu-Mn-Co系的热力学参数进行了优化，以再现各系的实验结果。计算结果与实验数据吻合较好。
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.
