Large Diameter Ingots Of Nickel Base Alloys
View pageUS Patent:
6719858, Apr 13, 2004
Filed:
Feb 4, 2002
Appl. No.:
10/066891
Inventors:
Betsy J. Bond - Monroe NC
Laurence A. Jackman - Monroe NC
A. Stewart Ballantyne - Charlotte NC
Laurence A. Jackman - Monroe NC
A. Stewart Ballantyne - Charlotte NC
Assignee:
ATI Properties, Inc. - Albany OR
International Classification:
C22C 1907
US Classification:
148428
Abstract:
A method of producing a nickel base alloy includes casting the alloy within a casting mold and subsequently annealing and overaging the ingot at at least 1200Â F. (649Â C. ) for at least 10 hours. The ingot is electroslag remelted at a melt rate of at least 8 lbs/min. (3. 63 kg/min. ), and the ESR ingot is then transferred to a heating furnace within 4 hours of complete solidification and is subjected to a novel post-ESR heat treatment. A suitable VAR electrode is provided form the ESR ingot, and the electrode is vacuum arc remelted at a melt rate of 8 to 11 lbs/minute (3. 63 to 5. 00 kg/minute) to provide a VAR ingot. The method allows premium quality VAR ingots having diameters greater than 30 inches (762 mm) to be prepared from Alloy 718 and other nickel base superalloys subject to significant segregation on casting.
