Neutron diffraction study of the deuterides of Ti–Mo alloys

The structures of the deuterides of seven Ti-Mo alloys with different Mo contents ranging from 5 to 40 at% are studied by neutron diffraction. After deuterization at similar to 150kPa, the saturated deuterides containing similar to 1.8-1.9 deuterium per alloy atom with a delta-phase titanium hydride type of structure have formed. The lattice constants of the deuterides decrease consistently with the increase of Mo content. The analysis of the line broadening of the diffraction patterns has revealed the relationship between lattice deformation and the contents of the alloying Mo in the deuterides. (c) 2006 Elsevier B.V.
