  • Publication number: 20130248061
    Abstract: Methods of processing compositions containing titanium and aluminum, especially titanium aluminide intermetallic compositions (TiAl intermetallics) based on the TiAl (gamma) intermetallic compound. The methods entail processing steps that include a hot isostatic pressing (HIP) cycle and a heat treatment cycle that can be performed in a single vessel. TiAl intermetallic compositions processed in this manner preferably exhibit a duplex microstructure containing equiaxed and lamellar morphologies.

  • Publication number: 20120251840
    Abstract: Nickel-base alloys suitable for use as a weld material to weld high-temperature components (10), such as turbine blades and vanes of gas turbine engines. The nickel-base alloys consist essentially of, by weight, 5 to 10 percent chromium, 3 to 14 percent cobalt, up to 4 percent molybdenum, 3 to 7 percent tungsten, 5 to 9 percent tantalum, 5 to 8 percent aluminum, 0.1 to 2 percent hafnium, 0.005 to 0.03 percent boron, up to 0.15 percent carbon, the balance being nickel and incidental impurities and/or residual elements. Welds (12) formed with the alloys are capable of exhibiting desirable levels of strength and oxidation resistance, while containing little if any rhenium.

  • Patent number: 8021604
    Abstract: A filler-metal weld rod of a filler-metal composition is prepared by providing a mass of metallic powders, mixing the metallic powders with a temporary thermoplastic binder to form an injection-moldable mixture, and thereafter injection molding the injection-moldable mixture at an injection-molding temperature above the thermoplastic temperature of the thermoplastic binder to form an injection-molded rod. Any excess thermoplastic binder is removed from the injection-molded rod, and the injection-molded rod is thereafter sintered to form a filler-metal weld rod, with the temporary thermoplastic binder removed in the step of sintering.
