Abstract: A method for manufacturing a turbine engine vane a root connected to a blade extending in a longitudinal direction includes the steps of providing a root; and providing mold with a first cavity and a second cavity that together define a recess in which the vane is formed. The recess includes a first space in which the blade is formed and a second space in which the root (1), c) is formed. The method further includes the steps of providing aluminum strips; positioning a fibrous reinforcement; arranging the vane root in the second space; and injecting a foam comprising aluminum or injecting an aluminum alloy into the first space of the recess of the mold such that the foam impregnates the fibrous reinforcement.

Abstract: The present disclosure relates to a hierarchical wear part including a reinforced portion comprising zirconia or an alumina-zirconia alloy. The reinforced portion also includes centimetric inserts with a predefined geometry. The inserts include micrometric particles of metal carbides, nitrides, borides, or intermetallic compounds bonded by a first metal matrix. The inserts are inserted into a reinforcement structure infiltrated by a second metal matrix, the reinforcement structure having a periodic alternation of millimetric areas of high and low concentration of micrometric particles of zirconia or alumina-zirconia alloy. The second metal matrix is different from the first metal matrix.

Abstract: A castable, moldable, or extrudable magnesium-based alloy that includes one or more insoluble additives. The insoluble additives can be used to enhance the mechanical properties of the structure, such as ductility and/or tensile strength. The final structure can be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final structure as compared to the non-enhanced structure. The magnesium-based composite has improved thermal and mechanical properties by the modification of grain boundary properties through the addition of insoluble nanoparticles to the magnesium alloys. The magnesium-based composite can have a thermal conductivity that is greater than 180 W/m-K, and/or ductility exceeding 15-20% elongation to failure.

Abstract: Use of Ca in metal matrix composites (MMC) allows for incorporation of small and large amounts of ceramic (e.g. rutile TiO2) into the metal (Al, or its alloys). Calcium remains principally out of the matrix and is part of a boundary layer system that has advantages for integrity of the MMC. Between 0.005 and 10 wt. % calcium (Ca) may be included, and more than 50 wt. % of rutile has been shown to be integrated. Rutile may therefore be used to reduce melt loss due to calcium from an aluminum or aluminum alloy melt.

Abstract: A method for forming localized binder in a drilling tool is disclosed. A method includes placing a reinforcement material in a matrix bit body mold, placing a localized binder material within the reinforcement material at a selected location in the matrix bit body mold, wherein the localized binder material confers a selected physical property at the selected location, placing a universal binder material in the matrix bit body mold on top of the reinforcement material, heating the matrix bit body mold, the reinforcement material, the localized binder material, and the universal binder material to a temperature above the melting point of the universal binder material, infiltrating the reinforcement material and the localized binder material with the universal binder material, and cooling the matrix bit body mold, the reinforcement material, the localized binder material, and the universal binder material to form a matrix drill bit body.

Abstract: An example mold assembly system includes a mold assembly including a mold forming a bottom of the mold assembly, a funnel operatively coupled to the mold, and an infiltration chamber defined at least partially by the mold and the funnel, the infiltration chamber being used for forming an infiltrated downhole tool. A mold assembly cap is positionable on the mold assembly and including a sidewall extendable about an outer periphery of the mold assembly at least partially along a height of the mold assembly. The sidewall exhibits a horizontal cross-sectional shape that accommodates a shape of the mold assembly and the sidewall is made of a thermal material that promotes directional solidification of the infiltrated downhole tool during fabrication.

Abstract: There is provided an apparatus and method for manufacturing of an infiltrated fiber-based composite film. The apparatus comprises two tool blocks arranged opposite each other enabling a fiber-based film to be arranged between the tool blocks. At least one of the tool blocks comprises a recess so that the recess can form a sealed cavity enclosing a portion of the film when the tool blocks are in contact with each other. At least one of the tool blocks comprises a vacuum channel connecting cavity to a vacuum pump for drawing a vacuum in the cavity; a melt channel connecting the cavity to a source of molten material. The melt channel comprises a valve arrangement controlling delivery of the molten material to the cavity; pressure means to achieve an elevated pressure onto the molten material within the cavity such that a fiber film in the cavity is infiltrated by the molten material; and an ejection piston for ejecting an infiltrated fiber film from the cavity.

Abstract: A method of manufacturing a degradable article comprises: forming a mixture comprising composite particles dispersed in a metallic matrix material; the composite particles comprising a carrier and a disintegration agent coated on the carrier or embedded in the carrier, or a combination thereof and having a density that is about 0.2 to about 2.5 equivalents to that of the metallic matrix material when measured under the same testing conditions; and molding or casting the mixture to form a degradable article. The disintegration agent forms a plurality of galvanic cells with the metallic matrix material, or the carrier, or a combination thereof, in the degradable article.
