摘要：

The detailed structural information of the deuteride of a null matrix Ti-Mo alloy containing 33 at.% of Mo is studied by complementation of the neutron and X-ray powder diffraction techniques. The deuteride containing similar to 1.8 deuterium atoms per alloy atom forms a titanium 8-hydride type of structure with deuterium atoms in the tetrahedral interstitial sites. The line broadening analysis of the deuteride phase suggests that the deuterization of the alloy causes strong lattice deformation effects, and the micro-strain is likely to be dislocation induced. In comparison with the deformation of the host Ti-Mo alloy matrix lattice, a relaxation effect is observed for the deformation of the interstitial deuterium sublattice. (c) 2006 Elsevier B.V.
