Abstract

Hydride phases based on d-metal-doped TiCr-alloys with the C14 Laves phase hexagonal structure were prepared. Hydride phases with an expanded C14 Laves phase structure and face-centered cubic (FCC) phases known from related literature were identified by X-ray diffraction in the prepared samples. The discovered FCC hydride phase was stable under ambient conditions, and after hydrogen desorption its lattice was transformed to a body-centered cubic (BCC) lattice. The lattice expansion in both TiCr-alloy structures correlates with the volume effects of the individual constituent metal hydride lattices.
