Abstract

A statistical moment method has been applied to study the melting of defective face-centered cubic (FCC) interstitial alloy γ-FeC under pressure up to 100 GPa. The theory of melting is based on the absolute stability limiting condition of the crystalline state. The relationship between the pressure, temperature, and concentration of equilibrium vacancies at the melting point of alloy γ-FeC is discussed and evaluated. The numerical results in limit cases are in good agreement with experiments and calculations by other authors, allowing reliable prediction of the melting features of alloy γ-FeC at high pressures.
