From: Metastable phase formation of Pt-X (X = Ir, Au) thin films
(a) Enthalpy of formation of Pt-Ir and Pt-Au systems calculated by ab initio and CALPHAD methods as a function of chemical composition, (b) CALPHAD determined Gibbs free energy of mixing data as a function of chemical composition at a temperature of 600 °C.
