Abstract

L'invention concerne un acier de construction anticorrosion à ultra-haute résistance renforcé par nano-précipitation. Cet acier présente une combinaison de résistance à une sollicitation externe et de résistance à la corrosion et comprend une combinaison en poids : d'environ 0,1 à 0,5 % de carbone (C), d'environ 8 à 17 % de cobalt (Co), de 0 à environ 10 % de nickel (Ni), d'environ 6 à 12 % de chrome (Cr), de moins d'environ 1 % de silicium (Si), de moins d'environ 0,5 % de manganèse (Mn) et de moins d'environ 0,15 % de cuivre (Cu) avec des additifs choisis dans le groupe constitué : de moins 3 % de molybdène (Mo), de moins 0,3 % de niobium (Nb), de moins 0,8 % de vanadium (V), de moins d'environ 0,2 % de tantale (Ta), de moins de 3 % de tungstène (W) et de combinaisons de ces éléments, avec des additifs supplémentaires choisis dans le groupe constitué : de moins 0,2 % de titane (Ti), de moins de 0,2 % de lanthane (La) ou d'autres éléments des terres rares, de moins de 0,15 % de zirconium (Zr), de moins de 0,005 % de bore (B) et de combinaisons de ces éléments, d'impuretés constituées : de moins d'environ 0,02 % de soufre (S), de 0,012 % de phosphore (P), de 0,015 % d'oxygène (O) et de 0,015 % d'azote (N), le reste étant constitué sensiblement de fer (Fe), d'éléments accessoires et d'autres impuretés. L'alliage est renforcé par des carbures nanométriques de M2C dispersés dans une matrice martensitique à réseau fin où la séparation du Cr en surface crée une couche stable d'oxyde de passivation résistante à la corrosion. L'alliage, qui présente une dureté UTS de 280 ksi, peut être utilisé pour les trains d'atterrissage des avions, pour les machines et les outils fonctionnant dans des environnements hostiles, et dans d'autres applications dans lequel ce type d'alliage est recherché.
