    Abstract: A method of depositing a multi-layer cladding (40) of superalloy material and an apparatus so formed. A first layer of material (20) is deposited on a substrate (22) such as by laser cladding of superalloy powder (54). The deposited material includes a directionally solidified region (24) and a topmost equiaxed region (26). The topmost region is removed such as by grinding to expose a flat surface (28) of directionally solidified material. A second layer of material (32) deposited onto the exposed flat surface will again have a directionally solidified region (34) and a topmost equiaxed region (36). The process is repeated until a desired thickness of cladding material is achieved, the multi-layer cladding having no equiaxed material between its layers throughout its thickness.

    Abstract: Occurrence of a casting defect in a cast-metal object is suppressed, and a crystal structure of the cast-metal object is made fine. When a cast-metal object is to be produced by using a casting mold, a metal material generating a free crystal during solidification is melted first. Subsequently, a molten metal including a melted metal material is poured into the casting mold. While the free crystal in the molten metal is deposited on a surface of the casting mold, the molten metal is solidified in the casting mold. Through the above steps, the molten metal is solidified in the casting mold, and the cast-metal object is produced.

  • Publication number: 20140072823
    Abstract: The invention relates to a generative production method for producing a component by selectively melting and/or sintering a powder several times consecutively by introducing an amount of heat by means of beam energy, such that the powder particles melt and/or sinter in layers, wherein the powder particles (1) are made of a first material (2) and the powder particles are surrounded by a second material (3) partially or over the entire surface thereof, wherein the second material has a lower melting point than the first material and/or lowers the melting point of the first material when mixed with the first material. The invention further relates to a corresponding powder and to a prototype produced from said powder.

  • Publication number: 20140060708
    Abstract: High modulus turbine shafts and high modulus cylindrical articles are described as are the process parameters for producing these shafts and cylindrical articles. The shafts/articles have a high Young's modulus as a result of having high modulus <111> crystal texture along the longitudinal axis of the shaft/article. The shafts are produced from directionally solidified seeded <111> single crystal cylinders that are axisymmetrically hot worked before a limited recrystallization process is carried out at a temperature below the recrystallization temperature of the alloy. The disclosed process produces an intense singular <111> texture and results in shaft or cylindrical article with a Young's modulus that is at least 40% greater than that of conventional nickel or iron alloys or conventional steels.

  • Publication number: 20140017113
    Abstract: Processes by which bulk forms can be produced in a single continuous operation, as opposed to multi-stage deformation processes that involve a series of separate and discrete deformation operations or stages. Such processes generally entail deforming a solid body using a large-strain extrusion machining technique and deformation conditions that obtain a predetermined crystallographic texture in the continuous bulk form that differs from the crystallographic texture of the solid body.

  • Publication number: 20130330228
    Abstract: An apparatus for producing a semi-solidified metal has a heating device which heats a metal material, a vessel, a cooling device which cools the vessel, and a pouring device which pours the metal material into the vessel. The vessel has a hollow member which configures a wall of the vessel and is opened at both of the upper and lower ends and into which the metal material is poured from the upper opening, and a bottom member which closes the lower opening of the hollow member and configures the bottom of the vessel. The cooling speed of the metal material by the bottom member is faster than the cooling speed of the metal material by the hollow member.
