Thermodynamic description of fcc and liquid phases of the Au-Pd binary was obtained using CALPHAD method. Several possible paarameter sets was obtained. To choose between those, calculation of liquidus surface of Au-Cu-Pd ternary was performed. Unusual and somewhat unexpected result is necessity of rather complicated model (three-term Guggenheim-Redlich-Kister polynomial) for liquid phase; solid phase proved to be subregular.
