Monocrystalline Alloys With Controlled Partitioning

View page
US Patent:
20050224144, Oct 13, 2005
Filed:
Nov 19, 2004
Appl. No.:
10/994202
Inventors:
Tresa Pollock - Ann Arbor MI, US
Qiang Feng - Ann Arbor MI, US
Laura Rowland - Ann Arbor MI, US
Maxim Konter - Klingnau, CH
Peter Holmes - Winkel, CH
International Classification:
C22C019/05
US Classification:
148404000, 148428000, 148429000
Abstract:
Nickel-based superalloys, for fabrication of monocrystalline turbine components to be used in industrial and aircraft turbine engines, having the following composition (in wt %): 5.6-8.1% Al, 4.1-14.1% Ru, 6.1-9.9% Ta, 3.6-7.5% Re, and the remaining balance Ni. The partitioning of alloying elements can be controlled to achieve a wide range of precipitate shapes and exceptional resistance to degradation under high temperature exposure conditions.

US Patent:
52701239, Dec 14, 1993
Filed:
Mar 5, 1992
Appl. No.:
7/846643
Inventors:
William S. Walston - Maineville OH
Earl W. Ross - Cincinnati OH
Kevin S. O'Hara - Boxford MA
Tresa M. Pollock - Pittsburgh PA
Assignee:
General Electric Company - Cincinnati OH
International Classification:
C22C 1905
C22F 110
US Classification:
428652
Abstract:
A nickel base superalloy capable of being made into a single crystal article is provided with high temperature strength and improved stability by limiting the Presence of an undesirable SRZ constituent. Significant to the control of formation of such undesirable constituents is the control of the amount of Re in the alloy in combination with elements such as Al, Cr, Ta, Mo, Co and W. A solution heat treatment is provided for additional control.
