Phase equilibria and thermodynamics of binary copper systems with 3 d -metals. II. The copper-vanadium system

摘要: Thermodynamic assessment of the Cu-V system was carried out using CALPHAD method. The excess heat capacity liquid phase taken into account in model its Gibbs free energy. Excess thermodynamic properties limiting solid solutions were represented by regular solution models. A self-consistent set parameters obtained data on mixing enthalpy and information equilibria. phases diagram along with metastable extension calculated this parameters. used order to predict composition limits formation supersaturated prepared highly nonequilibrium methods synthesis.
