Zusammenfassung:	A forging preform (200) for a turbine rotor (10) disk is disclosed. The preform (200) includes a body of a superalloy material (9) having a mass of about 5000 lbs or more, the superalloy material (9) having a substantially homogeneous grain morphology and an ASTM average grain size of 10 or smaller. A turbine rotor (10) disk is also disclosed. The disk includes a substantially cylindrical disk of a superalloy material having a mass of about 5000 lbs or more, the superalloy material (9) having a substantially homogeneous grain morphology and an ASTM average grain size of about 10 or smaller. A method (100) of making a turbine rotor disk is also disclosed. The method (100) includes providing a superalloy powder material (110) and pressing the superalloy powder (120) material to form a forging preform for a turbine rotor disk.
