    摘要： A gamma prime nickel-base superalloy and components formed therefrom that exhibit improved high-temperature dwell capabilities, including creep and hold time fatigue crack growth behavior. A particular example of a component is a powder metallurgy turbine disk of a gas turbine engine. The gamma-prime nickel-base superalloy contains, by weight, 18.0 to 30.0% cobalt, 11.4 to 16.0% chromium, up to 6.0% tantalum, 2.5 to 3.5% aluminum, 2.5 to 4.0% titanium, 5.5 to 7.5% molybdenum, up to 2.0% niobium, up to 2.0% hafnium, 0.04 to 0.20% carbon, 0.01 to 0.05% boron, 0.03 to 0.09% zirconium, the balance essentially nickel and impurities, wherein the titanium:aluminum weight ratio is 0.71 to 1.60.

    摘要： Various braze alloy compositions are described, along with methods for using them. In one instance, a boron-free, high-temperature braze alloy includes selected amounts of chromium, hafnium, and nickel. The braze alloy can be used, for example, as a component in a wide gap braze mixture where a higher or lower melting point superalloy and/or brazing powder is used. The braze alloys may permit joining or repairing of superalloy articles with complex shapes, and may be used in high temperature applications. In some other braze alloy embodiments, a nickel- or cobalt-based braze composition can contain selected amounts of boron, but includes restricted amounts of chromium.

    摘要： Braze materials and processes for using braze materials, such as for use in the manufacturing, coating, repair, and build-up of superalloy components. The braze material contains a plurality of first particles of a metallic material having a melting point, and a plurality of second particles comprising at least one nonmetallic material chosen from the group consisting of oxides, carbides, and nitrides of at least one metal. The nonmetallic material is more susceptible to heating by microwave radiation than the metallic material of the first particles, and the nonmetallic material is present in the braze material in an amount sufficient to enable the first particles to completely melt when the first and second particles are subjected to heating by microwave radiation.

    摘要： A shell mold for casting molten material to form an article is described. The mold includes a shell for containing the molten material, formed from at least one of yttrium silicates, zirconium silicates, hafnium silicates, and rare earth silicates. The mold also includes a facecoat disposed on an inner surface of the shell that contacts the molten material. The facecoat can be made from the materials described above. A method of casting a niobium-silicide article is also described, using the shell mold described herein. A method of making the ceramic shell mold is described as well, along with a slurry composition used in the manufacture of the shell mold.
