摘要：

The hydrides NiTiH(x) (x=1.0 and 1.4) have been prepared by a two-step method comprising an electrochemical treatment followed by a hydrogen gas pressure charging. The hydrides so obtained have a crystal structure of tetragonal symmetry and the hydrogen location has been determined by powder neutron diffraction. Hydrogen atoms occupy two octahedral sites. The hydrides do not present any structural phase transition as a function of temperature, in contrast to the parent alloy NiTi. The crystal structure is compared with other filled alloys of CsCl-type structure.
