The phase diagrams and thermodynamic properties in the Au-Fe and Na-Zn binary systems are assessed by the CALPHAD (CALculation of PHAse Diagram) method based on the experimental information in the literature, including enthalpies of mixing, activities and phase equilibrium data. The Gibbs free energies of the liquid, bcc, fcc phases are described by the substitutional solution model with the Redlick-Kister equation, and the intermetallic compound, NaZn13, in the Na-Zn binary system is treated as a stoichiometric phase. The self-consistent thermodynamic parameters of the Au-Fe and Na-Zn binary systems are obtained, from which good agreements between the calculated and experimentally measured data are evident for each binary system.
