Abstract

An in situ X-ray diffraction study of the high-pressure-phase evidenced a fct Ti sublattice. In the fco x-phase quenched under pressure, H atoms are displaced to octahedral sites, and the energy of H optic peak (at ~ 75 meV) is half that in other Ti-H phases where H occupy tetrahedral sites. Phase transformations on heating of x-TiH(D)0.75 were studied by neutron diffraction, small angle and inelastic neutron scattering (INS). Bound multiphonons were observed in the INS spectra of ordered γ-TiH(D).
