Abstract

L'invention concerne le procédé de fabrication d'un produit laminé d'épaisseur 0,5 à 10 mm en alliage base d'alliage d'aluminium comprenant notamment du cuivre et du lithium dans lequel après mise en solution et trempe on réalise un traitement thermique court dans lequel la tôle atteint une température comprise entre 145°C et 175°C pendant 0,1 à 45 minutes, la vitesse de chauffage étant comprise entre 3 et 600 °C/min. La tôle obtenue à l'issue du procédé selon l'invention présente une résistance élevée à la corrosion et est apte à être mise en forme pour la réalisation d'un élément de structure pour avion, notamment d'une peau de fuselage d'avion.
