Abstract
A hydrogen absorbing alloy for use in an environment where the alloy has the possibility of contacting oxygen is capable of inhibiting impairment of the hydrogen absorbing ability thereof when coming into contact with oxygen. The alloy has a composition represented in atomic ratio by Ti.sub.1-x Y.sub.x Mn.sub.y wherein x and y are in the range of 0<x.ltoreq.0.2 and 1.5.ltoreq.y.ltoreq.2.0, respectively, and comprises a C14-type crystal structure of Laves phase, the Laves phase having a segregaton phase of high Y concentration. Ti can be replaced by Hf and/or Zr within the range of over 0 to not greater than (1-x)/2 included in 1-x for the Ti atom. Mn can be replaced by V or Fe within the range of over 0 to not greater than y/2 included in y for the Mn atom. Mn is further replaceable by at least one element selected from the group consisting of Cr, Co, Ni, Cu and Al within the range of over 0 to not greater than y/2 included in y for the Mn atom, and can also be replaced by one of V and Fe at the same time when so required.
