Thermodynamic Assessment of the Cu-Th and Mo-Th Systems
The thermodynamic assessments of the Cu-Th and Mo-Th binary systems were carried out by using CALPHAD (Calculation of Phase Diagram) method on the basis of the experimental data including the thermodynamic properties and phase equilibria. The Gibbs free energies of the liquid, bcc, and fcc phases are described by the subregular solution model with the Redlich-Kister equation. Those of the four intermetallic compounds Cu6Th, Cu3.6Th, Cu2Th and CuTh2 in the Cu-Th binary system are described by the sublattice model. A set of self-consistent thermodynamic parameters are obtained, and the calculated phase diagram and thermodynamic properties are presented and compared with the experimental data from literatures. The calculated thermodynamic properties as well as phase diagrams agree well with the experimental data.
