Beschreibung
Zusammenfassung:	Practice of this invention provides, at least, a method of making a hydrogen storage material comprising the steps of:1. forming a molten mixture comprising nickel and at least one other transition metal element, the combination of which will form a TiNi alloy and including in said molten mixture from about 0.1 at. % to about 10 at. % of one or more elements which will form an alloy which is immiscible in the TiNi-type alloy; and(b) cooling said molten mixture to form a solid alloy-system material by rapid solidification of said molten mixture at a cooling rate of at least 103° C. per second.
