Beschreibung
Zusammenfassung:	A gamma prime nickel-based superalloy suitable for producing structural components (10), for example, turbine disks ( 10) and other turbomachinery components. The superalloy comprises an intentional amount of iron of up to 2.0 % and is preferably capable of exhibiting structural properties comparable to nickel-based superalloys without iron. The superalloy can be made using processes that lend themselves to advantageous scrap and revert usage of iron-containing alloys. The superalloy is free of an observable amount of sigma phase. La présente invention concerne un superalliage à base de nickel gamma-prime approprié pour produire des composants structurels (10), par exemple, des disques de turbine (10) et d'autres composants de turbomachine. Selon l'invention, le superalliage comprend une quantité voulue de fer allant jusqu'à 2,0 % et peut, de préférence, présenter des propriétés structurelles comparables à celles des superalliages à base de nickel exempts de fer. Le superalliage peut être réalisé au moyen de procédés qui se prêtent à une utilisation avantageuse de déchets et de recyclage d'alliages contenant du fer. Le superalliage est exempt de quantité observable de phase sigma.
