Thermodynamic assessments of the Mn-Sm and Mn-Ho systems

摘要：

By using the Calculation of Phase Diagrams(CALPHAD)method，the thermodynamic assessments of the Mn-Re(Re：Sm，Ho)systems were carried out based on the experimental data including thermodynamic properties and phase equilibria．Gibbs free energies of the solution phases(liquid，fee，bcc，hcp，rhombohedral_sm,cbcc A12 and cub_A13)were modeled by the subregular solution model with the Redlich-Kister formula,and those of the intermetallie compounds(Mn23Sm6，Mn2Sm,HoMn2，Ho6Mn23，HoMn12)were described by the sublattice model．An agreement between the present calculated results and experimental data iS obtained．
