US Patent:
20050238522, Oct 27, 2005
Filed:
Apr 22, 2004
Appl. No.:
10/830208
Inventors:
Todd Leonhardt - Medina OH, US
Clifford Guthman - Amherst OH, US
Assignee:
Rhenium Alloys, Inc. - Elyria OH
International Classification:
B22F003/12
US Classification:
419028000, 419029000, 419035000, 420433000
Abstract:
Rhenium-tungsten alloys including rhenium and from about 0.025% to less than about 10% by weight tungsten. The rhenium-tungsten alloys are formed by a process that includes coating rhenium metal powders with a liquid including a tungsten compound, drying the coated rhenium powder, compressing the dried coated powder to form a compact, and then sintering the compact to form the rhenium-tungsten alloy. The rhenium-tungsten alloys according to the invention exhibit mechanical properties that are superior to high-purity rhenium metal without a loss in ductility.
