Abstract
L'invention concerne l'industrie de la métallurgie. Elle concerne un superalliage à base de nickel, de grande résistance aux températures élevées et à la corrosion, qui contient, en poids, de 14 à 22 % de chrome, de 5 à 25 % de cobalt, de 1 à 5 % de tungstène, de 0,5 à 3 % de tantale, de 2 à 5 % de titane, de 1 à 4,5 % d'aluminium, la somme du titane et de l'aluminium étant de 4,5 à 9 %, de 0 à 2 % de niobium, plus de 0,3 à 1,2 % de bore, de 0 à 3,5 % de molybdène, de 0 à 0,5 % de zirconium, de 0 à 0,2 % au total d'yttrium ou de lanthane ou des deux, et de 0 à 0,1 % de carbone, le reste, outre les impuretés, étant constitué de nickel. Application à la production de pièces forgées ou moulées destinées à l'emploi dans une atmosphère corrosive et à température élevée, comme dans les turbines à gaz.
