Preparations of a Ti-Cr-V alloy were tried by applying pulsed electric current through compacted mixtures of TiO2, V2O5, Cr2O3 and C, and of TiH2, Cr and V after ball-milling into fine powder. TGA and DTA curves for a mixture of TiO2, V2O5, Cr2O3 and C showed that weight decreased up to about 1423 K. The Ti-Cr-V alloy could not be prepared from a mixture of TiO2, V2O5, Cr2O3 and C. However, from a mixture of TiH2, Cr and V, the Ti-Cr-V alloy formed together with phases of Cr1.93Ti1.07, Ti or C.
