Abstract

Technologie pour l'atomisation de grains de cristal d'alliage dont les constituants principaux sont des éléments faisant preuve d'une faible affinité avec l'hydrogène. Par rapport à l'alliage dont les constituants principaux sont des éléments faisant preuve de faible affinité avec l'hydrogène dans lesquels un élément exhibant une forte affinité avec l'hydrogène est présent, résultant de l'obtention de la présence d'un élément exhibant une forte affinité avec l'hydrogène dans un alliage dont les constituants principaux sont des éléments faisant preuve d'une faible affinité avec l'hydrogène, tout grain de cristal peut être super-atomisé en soumettant l'alliage au traitement thermique impliquant l'absorption et le dégagement d'hydrogène, obtenant ainsi une résistance super-élevée. Ainsi, les propriétés de l'alliage peuvent être améliorées et renforcées.
