Abstract
An alloy having a composition of the general formula, MmNi.sub.5-x A.sub.x-y B.sub.y, wherein Mm is misch metal, A is one member selected from the group consisting of Al, Cu, and Mn and B is one member selected from the group consisting of Al, Co, Cu, Fe, Mn, and Si, providing that both A and B do not represent one same compound, is useful for the occlusion of hydrogen.
Claims3
A quaternary alloy for the occlusion of hydrogen under low pressure, exhibiting low dissociation pressure of hydride and high speed of hydrogen release, the alloy having a composition represented by the following general formula:
- MmNi.sub.5-x A.sub.x-y B.sub.y
- wherein, Mm stands for misch metal, A for one element selected from the group consisting of Al, Cu, and Mn, B for one element selected from the group consisting of Al, Co, Cu, Fe, Mn, and Si, x for a numerical value in the range of from 0.1 to 2, y for a numerical value in the range of from 0.01 to 1.99, providing that both A and B do not represent the same element and the numerical value of x is greater than that of y.
