Gas turbine engines for future subsonic aircraft will probably have high pressure ratios which require nickel-base superalloy disks with 1300 to 1400 degrees F temperature capability. Several advanced disk alloys are being developed to fill this need. Under NASA's AST Program, manufacturing technologies for two advanced disk alloys, were studied by a team representing four engine companies, GEAE, PWA, Allied Signal, and Allison. GEAE and PWA focused their attention on an advanced disk alloy suitable for large engine applications developed under NASA's HSR Program, while Allied Signal and Allison opted to focus their attention on Alloy 10, a high strength nickel-base disk alloy. Eight heat treat options for Alloy 10 were studied by Allison and Allied Signal.
