Abstract

L’invention concerne un procédé de fabrication dans lequel on prépare un alliage comprenant 3,5 à 4,7 % en poids de Cu ; 0,6 à 1,2 % en poids de Li ; 0,2 à 0,8  % en poids de Mg ; 0,1 à 0,2 % en poids de Zr ; 0,0 à 0,3 % en poids d’Ag ; 0,0 à 0,8 % en poids de Zn ; 0,0 à 0,5% en poids de Mn ; au plus 0,20 % en poids de Fe + Si ; optionnellement un élément choisi parmi Cr, Sc, Hf et V, la quantité dudit élément, s’il est choisi, étant de 0,05 à 0,3 % en poids pour Cr et pour Sc, 0,05 à 0,5 % en poids pour Hf et pour V; autres éléments au plus 0,05% en poids chacun et 0,15% en poids au total, on introduit un affinant, on coule sous une forme brute, on homogénéise, déforme à chaud, met en solution, trempe, déforme à froid et réalise un revenu, dans lequel l’affinant contient des particules de TiC et/ou la déformation à froid est comprise entre 8 à 16% . Les produits obtenus par le procédé selon l’invention présentent un compromis avantageux entre résistance mécanique et ténacité. FIGURE d’ABREGE : Figure 1 FIGURES [FIG 1] [FIG 2]
