Abstract
To produce a hydrogen absorbing alloy powder which is an aggregate of alloy particles each including a metal matrix and added-components, an aggregate of metal matrix particles and an aggregate of added-component particles are used, and mechanical alloying is carried out. In this case, the relationship between the particle size D of the metal matrix particles and the particle size d of the added-component particles is set at d≦D/6. Thus, the milling time can be shortened remarkably.
Claims3
A process for producing a hydrogen absorbing alloy powder which is an aggregate of alloy particles each comprising a metal matrix and added-components, comprising the steps of:
- starting with, an aggregate of metal matrix particles and an aggregate of added-component particles, wherein a relationship between the particle size D of the metal matrix particles and the particle size d of the added-component particles is set at d≦D/6;
- mixing the aggregate of metal matrix particles and the aggregate of added-component particles having said relationship to form a mixture;
- and
- conducting one of mechanical alloying and mechanical grinding on said mixture.
