| Abstract: | A criterion on the evaluation of thermodynamic data of intermetallic compounds for Ti-Si-C ternary system is derived on the basis of the minimum energy principle and the nature of convex-downward surface. The Gibbs free energy of formation of binary-phases and ternary-phases in the Ti-Si-C system are estimated as an example. The thermodynamic data are reported for the first time. |
