Abstract

On parvient à une réduction de dimension de produits de cristallisation existant dans la structure de l'alliage d'Al de la série Al-Zn-Mg-Cu 7000 obtenu par une méthode de solidification par refroidissement rapide et tendant à devenir grossier par ségrégation d'éléments d'alliage, en contrôlant la vitesse de déposition, le rapport G/M, etc. de métal fondu pulvérisé au moment de la formation de la pulvérisation par un gaz inerte. En conséquence, il est possible de fournir un alliage d'Al qui a non seulement une résistance élevée et une ductilité élevée, mais encore une résistance élevée à la fatigue, présentant ainsi une excellente fiabilité comme partie ou élément structural, et un procédé de fabrication de cet alliage.
