Hydride phases based on Ta<SUB>0.33</SUB>V<SUB>0.67</SUB> alloy with partial replacement of its components with Ti and Nb

Using of the X-ray diffraction, the reaction products of hydrogen with a volume-centered cubic modification of the alloy Ta0.33V0.67 with partial replacement of its components with titanium and niobium were studied. It was found that the hydrogenation reaction of such alloys results in the formation of hydride samples with varied phase composition and different lattice types. Varying the amount of titanium and niobium in the composition of the Ta0.33V0.67 alloy affects the transition of the crystal lattice from cubic body-centered to face-centered. Hydrogenation of the Ta0.33V0.67 alloy with partial replacement of the components with titanium and niobium leads to the formation of stable hydrides.
