Abstract

By using the calculation of phase diagrams (CALPHAD) method, the thermodynamic assessments of the Mn-Sm and Mn-Ho systems were carried out based on the experimental data including thermodynamic properties and phase equilibria. Gibbs free energy of the solution phase (liquid, fcc, bcc, hcp, cbcc, rhombohedral and cub) were modeled by the subregular or regular solution model with the Redlich-Kister formula, and those of the intermetallic compounds (Mn₂₃Sm₆, Mn₂Sm, HoMn₂, Ho₆Mn₂₃, HoMn₁₂) were described by the sublattice model. An agreement between the present calculated results and experimental data is obtained.
