Experimental Determination of Phase Equilibria in the Co-Cr-V Ternary System

Abstract

The phase equilibria in the Co-Cr-V ternary system were investigated by means of optical microscopy, electron probe microanalysis and x-ray diffraction. Four isothermal sections of the Co-Cr-V ternary system at 800, 1000, 1100 and 1200 A degrees C were established. The experimental results show that: (1) no ternary compound was found in this system; (2) the sigma and (V, Cr) phases form the continuous solid solutions from the Co-Cr side to Co-V side in the isothermal sections at 800-1200 A degrees C.
