Abstract
Official abstract text for this publication.
A turbine rotor disk and a method of making the turbine rotor disk using solid state bonding techniques are disclosed. The turbine rotor disk includes a radially inner portion comprising a wrought nickel alloy having a yield strength of at least 126 ksi at 1,000° F. The turbine rotor disk also includes a radially outer portion bonded to the radially inner portion, said radially outer portion comprising a cast nickel alloy configured as a single crystal or with a grain size of ASTM 2 or larger.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of making a turbine rotor disk, comprising: providing a first preform corresponding to a radially inner portion of the turbine rotor disk, said first preform comprising a wrought nickel alloy having a yield strength of at least 126 ksi at 1,000° F.; providing a second preform corresponding to a radially outer portion of the turbine rotor disk, said second preform comprising a cast nickel alloy configured with a grain size of ASTM 2 or larger; and solid-state bonding the first and second preforms together under heat and pressure to form a turbine rotor disk including a radially inner portion comprising the first preform and a radially outer portion comprising the second preform; wherein bonding the first and second preforms together comprises inertia bonding the first and second preforms together. 2. The method of claim 1 , wherein providing the first preform comprises working a billet comprising the nickel alloy to form the first preform. 3. The method of claim 1 , wherein providing the second preform comprises casting the nickel alloy under conditions to form the nickel alloy of the second preform configured with a grain size of ASTM 2 or larger. 4. The method of claim 3 , wherein the second preform has a grain size of ASTM 1 or larger. 5. The method of claim 3 , wherein the second preform has a grain size of ASTM 0 or larger. 6. The method of claim 1 , wherein providing the first preform comprises working a billet comprising the nickel alloy to form the first preform, and wherein providing the second preform comprises casting the nickel alloy under conditions to form the nickel alloy of the second preform with a grain size of ASTM 2 or larger. 7. The method of claim 1 , wherein the first preform includes a portion corresponding to a bore of the turbine rotor disk, and the second preform includes a portion corresponding to a rim of the turbine rotor disk.
