THE LATTICE STABILITY OF METALS V, VANADIUM, CHROMIUM, COBALT AND NICKEL.

Abstract

The enthalpy and entropy differences between the b.c.c., h.c.p. and f.c.c. structures of the transition elements previously estimated for second and third row transition elements have been extended to vanadium chromium, cobalt and nickel by assuming that the stability parameters for these elements are equal to those estimated for their second and third row counterparts. The resulting free energy differences have been employed to compute eighteen binary phase diagrams between the V, Cr, Co and Ni group and other transition elements exhibiting different stable crystal structures. The computations, which are restricted to cases where miscibility gaps are absent, have been performed on the basis of ideal liquid, b.c.c., h.c.p. and f.c.c. phases in order to afford the clearest possible comparison with observed phase diagrams.
