Abstract
We have synthesized a hydride phase based on a TiZrHfMoTa high-entropy alloy with a body-centered cubic lattice. Hydride formation has been shown by X-ray and neutron diffraction to be accompanied by a cubic-to-tetragonal lattice transformation. Structure analysis of a deuteride based on the same alloy has made it possible to locate the deuterium atoms and determine their position parameters.
