摘要: A variety of problems related to modelling composition dependent Gibbs energies and other thermodynamic properties is discussed. The current procedure adopted in the CALPHAD method for intermediate metallic nonstoichiometric phases described analysed. Some possibilities towards more physical approaches are pointed out.
