THERMODYNAMIC ASSESSMENT AND APPLICATIONS OF TI-V-N SYSTEM

Experimental Ti-V-N phase diagram data have been thermodynamically ass essed and a consistent set of thermodynamic functions has been develop ed. 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 cases for solid stat e diffusion kinetics. This is applied to a numerical simulation of ter nary solidification processes of Ti-V-N alloys and to a discussion of the nitriding behaviour of R-V alloys. MST/3787.
