Zusammenfassung:	A forging preform for a turbine rotor disk is disclosed. The preform includes a body of a superalloy material having a mass of about 5000 lbs or more, the superalloy material having a substantially homogeneous grain morphology and an ASTM average grain size of 10 or smaller. 5. A turbine rotor 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 having a substantially homogeneous grain morphology and an ASTM average grain size of about 10 or smaller. A method of making a turbine rotor disk is also disclosed. The method includes providing a superalloy powder material and pressing the superalloy powder material to form a forging preform for a turbine rotor disk.
