  • Patent number: 9878370
    Abstract: A bimodal metal nanocomposite of ceramic nanoparticles in a metal or metal alloy matrix has a microstructure showing a first “hard” phase containing the ceramic nanoparticles in the metal or metal alloy matrix, and a second “soft” phase comprising only the metal or metal alloy with few or no ceramic nanoparticles. The stiffness and yield strength of the bimodal metal nanocomposite is significantly increased compared to the metal or metal alloy alone, while the ductility of the metal or metal alloy is retained. A process for making the bimodal metal matrix nanocomposite includes milling a powder mixture of micrometer-size metal flakes and ceramic nanoparticles for a time sufficient to embed the ceramic nanoparticles into the metal flakes.

  • Patent number: 9358644
    Abstract: A method prepares a repair material for and repairs a damage point in the surface of cast parts. Spray particles having the same cast structure as the cast part are used as materials. The particles are applied to the damage point by cold gas spraying. The cold gas spraying is performed such that the spray particles are not melted and, advantageously, the cast structure is retained after the spray particles contact the repair point. The repair point can thus be advantageously furnished with the same properties as the rest of the component to be repaired. The repair material can be produced in that a cast part having the required cast structure is reduced to small pieces.

The position where the metal is melted into the structure is formed along a layer of metal powder, wherein the location and intensity of the beam that strikes the metal layer is based on the three-dimensional structure and is controlled and directed by a processor. The instant invention comprises a novel dry state sonication step for removing metal powder that is not melted from the three dimensional structure.

    Abstract: A tubular target is formed of refractory metal or a refractory metal alloy. The target has at least one tubular portion X with a relative density RDx and at least one tubular portion Y with a relative density RDy. At least one tubular portion X has, at least in some regions, a larger outer diameter than a tubular portion Y at least in some regions. A density ratio satisfies the relation (RDy?RDx)/RDy?0.001. There is also described a method for producing a tubular target from refractory metal or refractory metal alloy by sintering and local deformation of different degree. The tubular target has a more uniform sputter removal over the entire surface area compared with prior tubular targets. The tubular targets do not exhibit any tendency to arcing or to particle regeneration.

    Abstract: A method of manufacturing an annular wall (46) of a combustion chamber (15) comprises depositing layers of a metal sequentially one upon the other to form layers of a spiral wall (45) of the combustion chamber (15). Each layer of metal is deposited in a spiral pathway (122). The ends (E1, E2) of the spiral wall (45) of the combustion chamber (15) are joined together to form the annular wall (46) of the combustion chamber (15). The ends (E1, E2) of the spiral wall (45) of the combustion chamber (15) are at the opposite ends of the spiral pathway (122).

  • Patent number: 8790571
    Abstract: A method for preparing an article is disclosed. The method comprises compacting a mixture of a first pre-alloyed powder and a lubricant to thereby form a green part having a green strength sufficient to permit mechanical handling; applying a slurry to a surface of the green part to thereby form a slurry coated green part, wherein the slurry comprises a second pre-alloyed powder, a binder, and a solvent; and heating the coated green part to a temperature below a solidus temperature of the first pre-alloyed powder and between a solidus temperature and a liquidus temperature of the second pre-alloyed powder to thereby solid state sinter the first pre-alloyed powder into a sintered core and to liquid state sinter the second pre-alloyed powder into a continuous alloy coating over the sintered core.

  • Publication number: 20140202163
    Abstract: Additive manufacturing techniques may be utilized to construct effusion plates. Such additive manufacturing techniques may include defining a configuration for an effusion plate having one or more internal cooling channels. The manufacturing techniques may further include depositing a powder into a chamber, applying an energy source to the deposited powder, and consolidating the powder into a cross-sectional shape corresponding to the defined configuration. Such methods may be implemented to construct an effusion plate having one or more channels with a curved cross-sectional geometry.

  • Patent number: 8758675
    Abstract: The invention relates to a method for fabricating an open-porous metal foam body with a nickel base alloy, to a metal foam body fabricated this way as well as advantageous applications for the separation of specific components and pollutants from fluid flows. On the occasion, according to the set object open-porous metal foam bodies which have improved mechanical properties, and in addition an enlarged specific surface and/or increased surface roughness are to be provided. During fabricating it is proceeded such that an open-porous base foam body made of nickel or a nickel base alloy is coated with a liquid binding agent. Subsequent to this, a mixture of a powdery nickel base alloy and an organic component the temperature of phase transformation of which is at least 30 degrees centigrade from its solid phase to the liquid phase is deposited. The temperature should then be below the respective temperature of phase transformation.

  • Patent number: 8734712
    Abstract: A method for manufacturing a cutting insert green body from a sinterable powder, a tool set for manufacturing the cutting insert green body by that method and the green body manufactured by the tool set. The tool set has axially moving upper and lower punches and radially moving side punches. The side punches move slidably on die rods. The side punches and die rods move in channels in a base body on which a cover plate is mounted. The upper and lower punches move in through holes in the cover plate and base body, respectively. The die rods are stationary during compaction of the sinterable powder. The upper, lower and side punches form surfaces of the green body and the die rods form some of the edges of the green body. The green body can have undercuts and the edges formed by the die rods can be non-linear in shape.
