Abstract

A thermodynamic description of the Ti-Cr-C ternary system is obtained based on a critical evaluation and limited experimental verification of the literature data reported on the ternary system and its binary subsystems. Using a minimum of only 3 adjustable parameters these calculations allow us to reproduce the experimentally determined solidification sequence, the invariant reaction temperatures, and the compositions of the participating liquidphase. The only exception is the reaction temperature for the ternary eutectic L<->TiC + Cr7C3+ Cr3C2. This discrepany seems to be connected with thedifficulty to calculate the binary eutectic L <-> Cr7C3 + Cr3C2 indicatingthat the simple model used for the description of the liquid phase should be replaced by a more complex model to obtain a better fit for this reaction temperature.
