Hydride Phases Based on TiZrNbTa(Mo1–xVx) (0 < x < 1) High-Entropy Alloys

We have synthesized hydride phases based on a series of TiZrNbTa(Mo1–xVx) (x = 0, 0.2, 0.4, 0.6, 0.8, 1.0) high-entropy alloys with a body-centered cubic lattice. X-ray diffraction characterization results show that, as a result of hydride formation reaction, the cubic lattice of the alloys transforms first into a tetragonal lattice and then into a face-centered cubic one. As the vanadium content of the alloys increases, the fraction of the cubic phase and hydrogen content rise.
