Abstract
Procédé de production d'un alliage Al-Zn-Cu-Mg à haute résistance possédant une résistance améliorée à la croissance des fissures de fatigue et une tolérance élevée aux détériorations. Ledit procédé consiste à couler un lingot de composition suivante (en pourcentage en poids) : Zn 5,5 9,5, Cu 1,5 3,5, Mg 1,5 3,5, Mn < 0,25, Zr < 0,25, Cr < 0,10, Fe < 0,25, Si < 0,25, Ti < 0,10, Hf et / ou V < 0,25, d'autres éléments ayant chacun une teneur inférieure à 0,05 et une teneur totale inférieure à 0,15, le reste étant de l'aluminium. Ce procédé consiste ensuite à homogénéiser et / ou à préchauffer le lingot après la coulée, à façonner le lingot à chaud et éventuellement à l'écrouir pour obtenir un produit façonné ayant plus de 50 mm d'épaisseur, à soumettre le lingot à un recuit de mise en solution, à tremper le produit traité thermiquement et à vieillir artificiellement le produit façonné et traité thermiquement. L'étape de vieillissement comporte un premier traitement thermique à une température de l'ordre de 105 ·C à 135 ·C pendant plus de 2 heures et moins de 8 heures, et un second traitement thermique à une température supérieure à 135 ·C, mais inférieure à 170 ·C, pendant plus de 5 heures et moins de 15 heures. Le produit obtenu selon ledit procédé présente une résistance à la déformation par compression dans le sens L à S/4 d'au moins 475 MPa, une résistance à la traction d'au moins 510 MPa et un allongement ST à S/2 d'au moins 3,0 %. La présente invention concerne un produit sous forme de plaque pouvant être soudé constitué dudit alliage Al-Zn-Cu-Mg à haute résistance, ayant une épaisseur supérieure à 50 mm, et un élément structural d'avion produit à partir dudit alliage.
