Theoretical assessment of thermodynamic and surface properties of Ag–Al–Au–Cu liquid alloy at different temperatures
Thermodynamic and surface properties of Ag–Al–Au–Cu liquid alloy were computed and analysed in the temperature range 1573–1873 K using different geometrical models. The energy interaction parameters of constituent binary subsystems of Ag–Al–Au–Cu were optimised in the framework of the Redlich–Kister polynomial using experimental data of enthalpy of mixing and excess entropy of mixing. The thermodynamic and surface properties of binary and ternary subsystems of the Ag–Al–Au–Cu system were also calculated to explore their effects in quaternary complex formation. The excess Gibbs free energy of mixing of the quaternary system was computed using General Solution Model, Kohler model, and Toop model at different cross-sections. These values calculated were found to be consistent with each other. The mixing tendency of the system was further validated by the computing activities of its monomers. The surface properties of the systems were computed using Butler model.
