Abstract (en)
[origin: WO2014058491A2] 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.
