Thermodynamic modeling of the Ag-Sr system

The CALPHAD method was employed to model thermodynamic properties of the Ag-Sr system. The liquid phase was treated as a substitutional model (Ag,Sr), with the excess molar Gibbs free energy expressed by the Redlich-Kister formula. All the intermetallic phases were modeled as stochiometric compounds. The solubilities of Ag and Sr in the terminal solid phases were not considered due to their negligible values. Calculated results were then compared with available data from existing literatures. A set of self-consistent thermodynamic parameters of the Ag-Sr binary system was obtained.
