Description
The A15 phase field in the system V-Ga was investigated by DTA and photomicroscopy, in order to determine the appropriate annealing conditions for inducing a maximum disorder in this compound by argon-jet quenching. The conditions of formation of a single-phase V3Ga alloy were studied. The long range order (LRO) parameter, S, of V3Ga has been refined from X-ray and neutron diffraction data obtained on the same sample after two greatly different heat treatments. A comparison between the temperature factor of V3Ga and that of other A15 type compounds shows a substantial difference between the values of high Tsub(c) superconductors such as V3Ga, V3Si, Nb3Al and Nb3Sn, and those of non super-conductors, such as V3Co and Cr3Si.
