Thermodynamic assessment of Ni-Ta-C ternary system
（Department of Materials Science and Engineering；State Key Laboratory of Powder Metallurgy; Central South University of Technology; Changsha 410083; P. R. China）
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.
Key words: nickel-tantalum-carbon systems; phase diagrams; thermody namics
