Webthe phase diagram, we can notice that the top point D of the phase diagram is the congruent melting point of the compound AB because the solid and liquid phases now have the same composition. - Congruent melting point represents a definite temperature just like the melting points of pure components. In the phase diagram, the Webcongruent melting point that is masked by the equilibrium phase diagram while metastable equilibria of congruently melting compounds usually form metastable eutectics with non-neighboring phases. In the present investigation, the stable W-C phase equilibria were reproduced using Gibbs energy data obtained from Gustafson’s optimization [3].
