Abstract
The material is derived from the compound TiNi, is a single-phase material and is expressed by the following general formula: EQU (Ti.sub.[1-(x+y)] Zr.sub.x M.sub.y)Ni.sub.z where: ##EQU1## where M is chosen from vanadium V, silicon Si, and a combination of vanadium and of silicon. Preferably, the hydridable material satisfies the following formulae: EQU (Ti.sub.0.7 Zr.sub.0.2 V.sub.0.1)Ni or EQU (Ti.sub.0.5 Zr.sub.0.4 Si.sub.0.1)Ni The hydridable material is a single-phase material and has a body-centered cubic lattice, with a lattice parameter of about 3 .ANG..
