Abstract

By using the calculation of phase diagrams (CALPHAD) method, the thermodynamic assessments of the Sc-M (M: Cr, Gd, Mo, W and Zr) binary systems were carried out based on the available experimental data including thermodynamic properties and phase equilibria. Gibbs free energies of the liquid, hcp and bcc phases in the Sc-M (M: Cr, Gd, Mo, W and Zr) binary systems were modeled by the substitutional solution model. An agreement between the present calculated results and experimental data was obtained.
