Abstract

La présente invention concerne des articles en superalliage à base de nickel à température de fusion supérieure à 1 288 degrés C et un procédé de fabrication. Le superalliage à base de nickel a une composition de 8 à 12 % de chrome, 4, 5 à 5,5 % d'aluminium, 1 à 2 % de titane, 3 à 5 % de tungstène, 10 à 14 % de tantale, 3 à 7 % de cobalt, le complément est essentiellement du nickel et cet alliage ne comprend pas de carbone de bore et de zirconium et contient seulement des quantités limitées de cobalt. L'invention est, par exemple, utilisable dans le domaine des moteurs à turbine à gaz.The present invention relates to nickel-based superalloy articles having a melting point above 1,288 degrees C and a method of making them. The nickel-based superalloy has a composition of 8 to 12% chromium, 4.5 to 5.5% aluminum, 1 to 2% titanium, 3 to 5% tungsten, 10 to 14% tantalum, 3 to 7% cobalt, the balance is mainly nickel and this alloy does not include boron and zirconium carbon and contains only limited amounts of cobalt. The invention is, for example, usable in the field of gas turbine engines.
