Abstract

The thermodynamic assessments of the Co-La and Mo-La systems have been carried out by using CALPHAD (Calculation of Phase Diagrams) method on the basis of the experimental data including thermodynamic properties and phase equilibria. Gibbs free energies of the solution phases (liquid, fcc, hcp, bcc and dhcp) were described by subregular solution models with the Redlich-Kister equation, and those of the intermetallic compounds were described by sublattice models. A consistent set of thermodynamic parameters has been derived for describing the Gibbs free energies of each solution phase and intermetallic compound in the Co-La and Mo-La binary systems. The calculated phase diagrams and thermodynamic properties in the Co-La and Mo-La systems are in good agreement with experimental data.
