Abstract
The phase diagram of the V-Ga system is refined by microstructural and thermal analysis, x-ray diffraction, measurements of microhardness and critical superconducting temperature, and also the determination of the chemical composition of certain phases by x-ray spectral microanalysis. The results are compared with published data. The effect of chemical composition and heat treatment on the superconducting temperature of the 0 phase (Cr3Si structure) is studied. The transformation temperature of the 3 phase is affected by the degree of ordering of its crystal structure and the degree of uniformity of the alloys. The maximum transformation temperature occurs for 26 at.% Ga. Gallium reduces the critical superconducting temperature of vanadium.
