High-entropy alloys (HEAs) typically contain four or more principle elements in approximately equimolar amounts. It was recently discovered by the co-proposer that a body-centered cubic HEA of TiVZrNbHf absorbs hydrogen to form a metal hydride with a hydrogen-to-metal ratio (H/M) of 2.5. Such a high H/M ratio has never before been observed for pure transition metal hydrides and requires occupation of interstitial sites that are not accessible for hydrogen in simpler alloys with the same structure. It has been suggested that the large H/M is due to large local lattice strain.The proposed project will investigate the local structure in the HEA TiVZrNbHf and the corresponding deuteride by neutron total scattering. We would also like to consider some related compounds that have varying levels of local lattice strain to investigate how this influence the short-range order in the metal matrix.
