Abstract
L'invention concerne le traitement thermique de certains alliages d'aluminium. On chauffe l'alliage jusqu'à une température de formation d'une solution solide pour dissoudre dans l'alliage les constituants pouvant précipiter. On refroidit ensuite l'alliage (de préférence par trempe à l'eau) puis on le soumet à un survieillissement pour former des précipités par chauffage à une température supérieure au durcissement par précipitation mais inférieure à la formation d'une solution solide. On déforme plastiquement l'alliage à une température égale ou inférieure à celle du survieillissement puis on le maintient à une température de recristallisation : les précipités obtenus sont des germes de formation de nouveaux grains dont le développement donne la structure souhaitée. On peut ainsi améliorer les caractéristiques mécaniques de divers alliages d'aluminium pour la construction.
