Abstract

 This paper shows the thermodynamic analysis and predictions of metastable binary alloy silver- copper (Ag-Cu) system using the Calphad approach. The thermodynamic analysis involves the calculation of phase diagram, Gibbs energy of mixing, excess Gibbs energies, thermodynamic molar activities and coefficient of activities, partial and integral values of enthalpy for (Ag-Cu) alloy system at three elevated temperatures, (1973 K, 2000 K, 2028 K). The given alloys show positive deviation from Vegard's law, Henry's law and corresponding good negative deviation from Raolts's law ideal Gibbs curve. The activity simulation of the adding compositions are seen good attractive interaction for best doping characteristics. The alloy is seen equilibrium fluctuation and good stability.
