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-type 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.
La mise en pratique de cette invention met en oeuvre, au moins un procédé de production d'un matériau de stockage d'hydrogène comprenant les étapes consistant: 1) à former un mélange en fusion contenant du nickel ainsi qu'au moins un autre élément métallique de transition, la combinaison desquels forme un alliage de type TiNi et contenant dans ledit mélange en fusion environ 0,1 at % à environ 10 at % d'un ou de plusieurs éléments formant un alliage non miscible à l'alliage de type TiNi; et (b) à refroidir ledit mélange en fusion pour former un matériau à système d'alliage solide par solidification rapide dudit mélange en fusion à une vitesse de refroidissement d'au moins 10?3¿ ·C par seconde.
