Thermodynamic modeling of Ti-Fe-Cr ternary system

Previous work of the Ti-Fe-Cr ternary system and its related binary systems are reviewed. Based on the thermodynamic descriptions of the Ti-Fe, Ti-Cr and Fe-Cr systems available in the literature, and also the ternary experimental data previously reported, the Ti-Fe-Cr ternary system is reassessed in this work by means of the Calphad method. Isothermal sections at 923 K, 1073 K and 1273 K and three invariant reactions as well as the vertical section TiCr2-TiFe2 are calculated. It is shown that the present calculated results are in good agreement with most of the experimental data.
