Abstract
a. L'invention concerne des alliages fer-nickel-chrome durcissables par vieillissement assurant une précipitation. b. Ces alliages ont une morpholie compacte de phase gamma " enveloppant la phase gamma ' et sont constitués essentiellement de 40 à 50 % de nickel, 7,5 à 14 % de chrome, 1,5 à 4 % de niobium, 0,25 à 0,75 % de silicium, 1 à 3 % de titane, 0,1 à 0,5 % d'aluminium, 0,02 à 0,1 % de carbone, 0,002 à 0,015 % de bore, 0 à 3 % de molybdène, 0 à 2 % de manganèse, 0 à 0,01 % de magnésium, 0 à 0,1 % de zirconium et fer pour le reste c. Ces alliages sont préférés pour des applications exigeant une faible capacité d'absorption des neutrons, de bonnes propriétés mécaniques aux températures élevées et une bonne résistance au gonflement sous irradiation.
