Thermodynamic assessment and applications of Ti-V-N system

Abstract

Experimental Ti-V-N phase diagram data have been thermodynamically assessed and a consistent set of thermodynamic functions has been developed. Calculations have been performed to reveal some important features of the system. Problem areas in experimental data are indicated. The thermodynamic calculation is linked with limiting casesfor solid state diffusion kinetics. This is applied to a numerical simulation of ternary solidification processes of Ti-V-N alloys and to a discussion of the nitriding behaviour of Ti-V alloys.
