Iron-Aluminum Alloys Having High Room-Temperature And Method For Making Same

View page
US Patent:
52386457, Aug 24, 1993
Filed:
Jun 26, 1992
Appl. No.:
7/904802
Inventors:
Vinod K. Sikka - Oak Ridge TN
Claudette G. McKamey - Knoxville TN
Assignee:
Martin Marietta Energy Systems, Inc. - Oak Ridge TN
International Classification:
C21D 800
C22C 3806
US Classification:
420 79
Abstract:
Iron-aluminum alloys having selectable room-temperature ductilities of greater than 20%, high resistance to oxidation and sulfidation, resistant pitting and corrosion in aqueous solutions, and possessing relatively high yield and ultimate tensile strengths are described. These alloys comprise 8 to 9. 5% aluminum, up to 7% chromium, up to 4% molybdenum, up to 0. 05% carbon, up to 0. 5% of a carbide former such as zirconium, up to 0. 1 yttrium, and the balance iron. These alloys in wrought form are annealed at a selected temperature in the range of 700. degree. C. to about 1100. degree. C. for providing the alloys with selected room-temperature ductilities in the range of 20 to about 29%.

Iron Aluminide Alloys With Improved Properties For High Temperature Applications

US Patent:
49619039, Oct 9, 1990
Filed:
Mar 7, 1989
Appl. No.:
7/319771
Inventors:
Claudette G. McKamey - Knoxville TN
Chain T. Liu - Oak Ridge TN
Assignee:
Martin Marietta Energy Systems, Inc. - Oak Ridge TN
International Classification:
C22C 3806
US Classification:
420 79
Abstract:
An improved iron aluminide alloy of the DO. sub. 3 type that has increased room temperature ductility and improved high elevated temperature strength. The alloy system further is resistant to corrosive attack in the environments of advanced energy corrosion systems such as those using fossil fuels. The resultant alloy is relatively inexpensive as contrasted to nickel based and high nickel steels currently utilized for structural components. The alloy system consists essentially of 26-30 at. % aluminum, 0. 5-10 at. % chromium, 0. 02-0. 3 at. % boron plus carbon, up to 2 at. % molybdenum, up to 1 at. % niobium, up to 0. 5 at. % zirconium, up to 0. 1 at. % yttrium, up to 0. 5 at. % vanadium and the balance iron.

Corrosion Resistant Iron Aluminides Exhibiting Improved Mechanical Properties And Corrosion Resistance

US Patent:
53208021, Jun 14, 1994
Filed:
May 15, 1992
Appl. No.:
7/884530
Inventors:
Chain T. Liu - Oak Ridge TN
Claudette G. McKamey - Knoxville TN
Peter F. Tortorelli - Knoxville TN
Stan A. David - Knoxville TN
Assignee:
Martin Marietta Energy Systems, Inc. - Oak Ridge TN
International Classification:
C22C 3806
US Classification:
420 81
Abstract:
The specification discloses a corrosion-resistant intermetallic alloy comprising, in atomic percent, an FeAl iron aluminide containing from about 30 to about 40% aluminum alloyed with from about 0. 01 to 0. 4% zirconium and from 0. 01 to about 0. 8% boron. The alloy exhibits considerably improved room temperature ductility for enhanced usefulness in structural applications. The high temperature strength and fabricability is improved by alloying with molybdenum, carbon, chromium and vanadium.
