  • Patent number: 10731857
    Abstract: A liner of a combustor wall assembly generally defines a combustion chamber and includes a film cooling circuit having a channel communicating through a hot face of a substrate of the liner. An aperture of the circuit is defined by the substrate, extends through the cold face and is in fluid communication with the channel. The hot face of the substrate is covered with a coating that extends over and thus defines in-part the channel. A film cooling hole extends through the coating and is in fluid communication with the channel. A method of manufacturing the circuit includes casting the substrate with the aperture and hole; then placing an insert into the channel prior to application of the coating over the substrate and insert. The insert is then removed and the film cooling hole is formed through the coating.

  • Patent number: 8916005
    Abstract: A slurry and slurry coating process for forming a diffusion aluminide coating on a substrate, including internal surfaces within the substrate. The process involves preparing a slurry of a powder containing a metallic aluminum alloy having a melting temperature higher than aluminum, an activator capable of forming a reactive halide vapor with the metallic aluminum, and a binder containing an organic polymer. The slurry is applied to surfaces of the substrate, which is then heated to burn off the binder, vaporize and react the activator with the metallic aluminum to form the halide vapor, react the halide vapor at the substrate surfaces to deposit aluminum on the surfaces, and diffuse the deposited aluminum into the surfaces to form a diffusion aluminide coating. The process can be tailored to selectively produce an inward or outward-type coating. The binder burns off to form an ash residue that can be readily removed.

The ultrasound compression wave energy and impulse impacts impart compressive residual stress to the workpiece thereby decreasing tensile stresses in the sensitized metal and modifying the grain structure of the workpiece. These changes to the structure of the workpiece combine to slow the rate of enrichment of alloying elements at grain boundaries within the area of sensitized metal, cause intergranular diffusion of alloying elements in the area of sensitized metal, return a portion of alloying elements in the area of sensitized metal to solution and reduce or eliminate substantially straight intergranular paths through the workpiece.

  • Patent number: 8685183
    Abstract: Metal ingots for forming single-crystal shape-memory alloys (SMAs) may be fabricated with high reliability and control by alloying thin layers of material together. In this method, a reactive layer (e.g., aluminum) is provided in thin flat layers between layers of other materials (e.g., copper and layers of nickel). When the stacked layers are vacuum heated in a crucible to the melting temperature of the reactive layer, it becomes reactive and chemically bonds to the other layers, and may form eutectics that, as the temperature is further increased, melt homogeneously and congruently at temperatures below the melting temperatures of copper and nickel. Oxidation and evaporation are greatly reduced compared to other methods of alloying, and loss of material from turbulence is minimized.

    Abstract: A metal laminate is made by first laying at least one first metal strip of at least one first metal having a thickness of 40 ?m to 750 ?m on at least one second metal strip of a second metal different from the first metal to form a multilayer stack having a total thickness between 2 mm and 15 mm. Then the first and second strips of the multilayer stack are bonded together by rolling. Finally a finished laminate is formed by reducing a thickness of the bonded-together first and second strips by rolling in at least one pass such that the one first metal strip has a thickness of 0.5 to 10 ?m.

    Abstract: A method of making a beam-box crash management system comprises forming a first shell (100a) from a first sheet metal blank by a hot forming process. The first shell has a high tensile strength beam portion (102a) and integrally formed there-with a first low yield strength crash box portion (104a) proximate a first end of the beam portion and second low yield strength crash box portion proximate a second end of the beam portion. The first shell also has an open face extending continuously along the beam portion and each of the first and second crash box portions (104a, 106a). A closing element (100b) is formed from a second sheet metal blank, and is fixedly secured adjacent to the open face of the first shell.

  • Patent number: 8387228
    Abstract: A method for producing a single-clad or multiple-clad product includes providing a welded assembly comprising a cladding material disposed on a substrate material. Both the substrate material and the cladding material are individually selected alloys. At least a first edge of the cladding material of the welded assembly does not extend to a first edge of the substrate material and thereby provides a margin between the first edges. A material that is an alloy having hot strength greater than the cladding material is within the margin and adjacent the first edge of the cladding material. The welded assembly is hot rolled to provide a hot rolled band, and the material within the margin inhibits the cladding material from spreading beyond the edge of the substrate material during the hot rolling. In certain embodiments of the methods, the substrate material is stainless steel and the cladding material is nickel or a nickel alloy.

    Abstract: Guide wire devices and methods for their manufacture. The guide wire devices described herein include an elongate guide wire member that includes at least one section fabricated from a nickel-titanium (Ni—Ti) alloy that exhibits an elevated plateau stress and a narrowed stress hysteresis profile (e.g., a plateau stress of about 500 MPa to about 820 MPa and a stress hysteresis width in a range from about 250 MPa to about 80 MPa). Raising the plateau stress and narrowing the stress hysteresis width of Ni—Ti used in a guide wire device can significantly improve the steerability of the guide wire device while maintaining the flexibility, durability, and kink resistance that is typical of superelastic Ni—Ti alloys.
