Abstract
The phase diagrams of the Ho-Sb and Sb-Yb binary systems have been evaluated by using the CALPHAD (CALculation of PHAse Diagram) method with experimental data including the phase equilibria and thermodynamic properties. The Gibbs free energies of the liquid, bcc_A2, fcc_A1, hcp_A3, and rhombohedral_A7 phases were modeled by the subregular solution model with the Redlich-Kister formula, and those of the intermetallic compounds (Ho5Sb3, alpha Ho4Sb3, beta Ho4Sb3, alpha HoSb, beta HoSb, HoSb2, Sb2Yb, SbYb, Sb10Yb11, Sb3Yb4, alpha Sb3Yb5, and beta Sb3Yb5) in these two binary systems were described by the two-sublattice model. An agreement between the present calculated results and experimental data was obtained. (C) 2012 Elsevier Ltd. All rights reserved.
