Thermodynamic modeling of carbonitride formation in steels with V and Ti

A critical analysis of the available thermodynamic data for the Fe-V-Ti-C-N system has been performed, and a self-consistent thermodynamic description of this system has been proposed based on the CALPHAD (calculation of phase diagrams) method. Using the constructed thermodynamic description, we calculated the phase equilibrium states of the system under study and considered some laws of the effect of the alloy composition on the phase...
