Abstract:By means of the CALPHAD technique, an ideal calculation, i. e. without ternary interaction parameter, was applied to assess the Ni-Ta-C ternary system. The calculated and experimental data were in reasonable agreements. It proved the CALPHAD technique of a Powerful approach of the extrapolation, as well as the good feasibility of the thermodynamic descriptions of three binary systems, Ni-C, Ni-Ta and Ta-C.
