Abstract

L'invention concerne un procédé destiné au vieillissement artificiel d'alliages aérospaciaux d'aluminium de la Série 7000 pour les rendre plus solides et/ou plus résistants à la corrosion. Ce procédé consiste à ajouter volontairement un deuxième palier/étape de vieillissement au revenu à un seul palier, ou un troisième palier/étape à une opération de vieillissement à deux paliers, faible et élevé. Le palier/étape ajouté est effectué à une température comprise entre 225-275 ·F environ pendant 3 à 24 heures environ. De préférence, le palier supplémentaire est effectué à 250 ·F environ pendant au moins 6 heures.
