Abstract:
A hydrogen-absorbing alloy having a composition expressed by the general formula Ti.sub.x Cr.sub.y V.sub.z, where each of x, y and z represents an atomic percent and satisfies the relation x+y+z=100, wherein the composition has a body-centered cubic structural phase as a principal phase, said principal phase exists within the range in which said body-centered cubic structure appears and a spinodal decomposition occurs with the exception of a C14 Laves phase, and the spinodal decomposition forms a periodic structure having a spacing of 1.0 mm to 100 nm, and its apparent lattice constant is at least 0.2950 nu but it is not greater than 0.3060 nm.
