Abstract

L'invention concerne un procédé de fabrication d'un produit en plaque d'alliage d'aluminium de série 7xxx présentant une résistance à la rupture par fatigue améliorée, le procédé comprenant les étapes consistant à : a) couler un lingot constitué d'un alliage d'aluminium de la série 7xxx comprenant (en % en poids) : Zn 5 à 9, Mg 1 à 3, Cu 0 à 3, le reste étant de l'aluminium et des éléments incidents et des impuretés; (b) homogénéiser et/ou préchauffer le lingot coulé; (c) laminer à chaud le lingot en un produit de plaque par laminage du lingot avec de multiples passes de laminage, caractérisé en ce que lorsque l'épaisseur intermédiaire de la plaque est comprise entre 80 et 220 mm, au moins une passe de laminage à chaud à réduction élevée est réalisée avec une réduction d'épaisseur d'au moins 25 %, le produit de plaque ayant une épaisseur finale inférieure à 75 mm. L'invention concerne également un produit en plaque d'alliage d'aluminium et un élément structural aérospatial produit par ce procédé.
