Synthesis of Hydride Phases Based on TiZrNbMoTa High-Entropy Alloy

A high-entropy TiZrNbMoTa alloy with a body-centered cubic lattice has been synthesized. The interaction of the alloy with hydrogen is accompanied by the formation of samples containing hydride phases with tetragonal and cubic lattices. Hydrogen desorption from the hydride at a high temperature leads to the formation of a fine metal powder of the original alloy with the cubic lattice. Samples of the alloy and hydride phases are analyzed by X-ray diffraction and electron microscopy.
