Abstract

La présente invention concerne un alliage fer-nickel-chrome. Cet alliage est caractérisé par le fait qu'il comprend, en poids, 29 à 34 % de nickel, 10 à 14 % de chrome, 1,5 à 2,5 % de titane, 0,95 à 4,3% de niobium ou de tantale ou de mélanges de ceux-ci, sous cette réserve que %Nb + 1/2 (%Ta) - de 0,95 à 2,15 % et que %Ti + 1/3Ø%Nb + 1/2(Ta)õ - au moins 2 % 0,002 à 0,015 % de bore, au maximum 2 % de manganèse, au maximum 0,5 % de silicium, au maximum 0,8 % d'aluminium, au maximum 0,1 % de carbone, au maximum 0,5 % de molybdène, au maximum 0,5 % de tungstène, le reste étant formé, à part les impuretés et les éléments accidentels, de fer à raison d'au moins 45 %. Cet alliage convient à la fabrication de pièces de turbines e à d'autres applications à températures intermédiaires.
