Determination of phase equilibria in the Ni–V–Nb–Ta–Cr–Mo–W system at 1375 K using the graph method

Abstract

Using the graph method the analysis of the phase equilibria in 35 quaternary systems, 21 quinary systems, seven six-component systems and the seven-component system Ni–V–Nb–Ta–Cr–Mo–W have been realised at 1375 K. The phase equilibria of the quaternary systems have been experimentally established. On the basis of the results obtained the phase equilibria in the Ni–V–Nb–Ta–Cr–Mo–W system at 1375 K have been determined.
