More Information
Summary:The present invention relates to a nickel-based alloy comprising, in weight percent: - 4.0 to 20.0% cobalt; - 14.0 to 18.5% chromium; - 1.8 to 2.6% aluminium; - 1.3 to 1.9% titanium; - 5.5 to 6.5% tantalum; - 0.01 to 0.10% carbon; - 0.003 to 0.02% boron; and - 0.01 to 0.10% zirconium. The present invention also relates to a method for manufacturing a part made of the nickel-based alloy, the method comprising: - preparing a billet that has the same composition as that of the nickel-based alloy; - shaping the part; and - heat treating the part. La présente invention concerne un alliage à base de nickel, comprenant en pourcentage massique : - 4,0 à 20,0 % de cobalt; - 14,0 à 18,5 % de chrome; - 1,8 à 2,6 % d'aluminium; - 1,3 à 1,9 % de titane; - 5,5 à 6,5 % de tantale; - 0,01 à 0,10 % de carbone; - 0,003 à 0,02 % de bore; et - 0,01 à 0,10 % de zirconium. La présente invention concerne également un procédé de fabrication d'une pièce en l'alliage à base de nickel, le procédé comprenant : - l'élaboration d'une billette dont la composition est celle de l'alliage à base de nickel; - la mise en forme de la pièce; et - le traitement thermique de la pièce.
