摘要

The experimental phase diagram data of the C-Cr-Ta ternary system available in the literature were critically reviewed. A thermodynamic modeling of the ternary system was then conducted by taking into account the literature data including the isothermal sections and invariant reactions. A set of self-consistent thermodynamic parameters for the Gibbs energies of individual phases in the C-Cr-Ta system was obtained by using the CALPHAD approach. Comprehensive comparisons between the calculated and measured phase diagrams show that all the reliable experimental information is satisfactorily accounted for by the present thermodynamic description.
