Method For Eliminating Low Cycle Fatigue Cracking In Integrally Bladed Disks
US Patent:
4536932, Aug 27, 1985
Filed:
Nov 22, 1982
Appl. No.:
6/443516
Inventors:
Roy L. Athey - North Palm Beach FL
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
B21K 304
B23P 1502
B23P 1502
US Classification:
291568B
Abstract:
Stress relief for the rim of an integrally bladed rotor made from a forging preform is provided by forming a plurality of radially extending circumferentially spaced-apart slots around the periphery of the preform. The slots are forged closed in a subsequent forming step. An oxide layer on the slot surfaces prevents the surfaces from bonding together when forged closed. The blades are formed between slots during the forging or by machining after forging.
Superalloy Forging Process
US Patent:
5693159, Dec 2, 1997
Filed:
Jan 10, 1994
Appl. No.:
8/180755
Inventors:
Roy L. Athey - North Palm Beach FL

Assignee:
United Technologies Corporation - Hartford CT
International Classification:
C22F 110
US Classification:
148677
Abstract:
A process for producing a fine grain forged superalloy article having a high yield strength at intermediate temperatures. A preferred starting composition comprises, by weight, 15% Cr, 13. 6% Co, 4. 1% Mo, 4. 6% Ti, 2. 2% Al, 0. 01% C, 0. 007% B, 0. 07% Zr, balance Ni. This material is forged at a temperature above the gamma prime solvus and at a true strain of at least 0. 5. Alternately, the material may be forged below the gamma prime solvus temperature with intermediate super solvus anneals. The overaged material is then worked at a temperature below the gamma prime solvus. The resultant fine grain material is then heat treated or can be further isothermally forged prior to heat treatment to produce complex shapes.
Method Of Producing Turbine Disks
US Patent:
4608094, Aug 26, 1986
Filed:
Dec 18, 1984
Appl. No.:
6/682968
Inventors:
John A. Miller - Jupiter FL
Roy L. Athey - North Palm Beach FL
Roy L. Athey - North Palm Beach FL
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
C22F 110
US Classification:
148 115N
Abstract:
A method is described for producing metallic articles, especially turbine disks, which have a hot-worked structure in one region and a warmworked structure in another region and thereby have properties which differ in different regions. The method comprises an initial hot-working step, an intermediate heat treatment step and a final warm-working step.
