Abstract

Hydrogen trapping at dislocations in deformed PdH0.0008 has been investigated with a combination of incoherent inelastic neutron scattering (IINS) and advanced computational techniques. The results from the IINS measurements indicate the formation of the hydride phase at dislocations at 4 K. Density functional theory results of a relaxed lattice containing an edge dislocation split into partials exhibit large local volumetric dilatation associated with hydrogen in near-core interstitial sites.
