ABSTRACT:
There is provided a hydrogen occluding alloy exhibiting high absorption and desorption speeds. A hydrogen occluding alloy comprising as an overall composition: 25 to 45 weight % Zr+Hf, wherein the Hf comprises not more than 4%, 1 to 15 weight % Ti, 10 to 20 weight % Mn, 2 to 12 weight % V, 0.6 to 5 weight % rare earth elements, and a balance Ni (of which content is not less than 25 weight %) and unavoidable impurities, and basically having a three-phase structure consisting of: a net-shaped continuous phase which is made of a Ni--Zr type alloy, a main phase (in the net-shaped continuous phase) made of a Zr--Ni--Mn based alloy, and a dispersed granular phase made of a rare earth elements-Ni type alloy distributed along the net-shaped continuous phase.
