Thermodynamic analysis and phase equilibria in iron-chromium-carbon system

The thermodynamic analysis of three component system Fe-Cr-C was carried out with the use of sublattice model. The results of calculation of phase equilibria are represented by isothermal sections and phase diagrams. The scheme of phase transmutations in this system is shown with the comparison of binary systems. Polythermic sections with the constant chromium concentration in the alloy are calculated and plotted.
