Abstract
Abstract An alloy represented by the general formula Tix-yZryCr2-zMnz, where 1 </= x </= 1.3, 0 < y </= 1, and 0 < z < 2. This alloy readily forms complex metal hydrides at low hydrogen pressures and can absorb a large quantity of hydrogen. The absorbed hydrogen can readily be liberated at room temperature.
