  • Moderated nuclear cask composite
    Patent number: 11951545
    Abstract: A cask liner includes a hollow cylinder comprising a boron-containing composition. The hollow cylinder has no longitudinal joints. The hollow cylinder may be formed as a single unit by isostatic pressing, for example by hot isostatic pressing (HIP) of a blend of a boron-containing powder and an aluminum or aluminum alloy powder which is blended by mechanical alloying. Casked nuclear fuel includes a nuclear fuel rod comprising uranium, which is disposed in or extends through the hollow cylinder of the cask liner.

  • LIGHT WEIGHT HIGH STIFFNESS METAL COMPOSITE
    Publication number: 20160303649
    Abstract: Metal matrix composites are disclosed that have a low coefficient of thermal expansion and low density. The composite includes a matrix formed from a low CTE metal alloy in which micron-scale ceramic particles are homogeneously dispersed therein. Methods for producing such composites are also disclosed. The composites also have improved yield strength and specific modulus.

  • ANODIZED METAL MATRIX COMPOSITE
    Publication number: 20160298254
    Abstract: Metal matrix composite articles are made with a substrate and an anodized layer. The anodized layer includes matrix phase and a dispersed phase of reinforcement particles in the matrix, the matrix being an oxide of aluminum or an aluminum alloy. The ratio of the thickness of the anodized layer to the average particle size (D50) of the reinforcement particles is at least 1.3.

  • LIGHTWEIGHT, ROBUST, WEAR RESISTANT COMPONENTS COMPRISING AN ALUMINUM MATRIX COMPOSITE
    Publication number: 20160273081
    Abstract: Rotor, disc, chain ring, and sprocket components are manufactured from a fine particle reinforced metal matrix composite material. The metal matrix composite may be an aluminum or aluminum alloy matrix. The fine reinforcement particles have a particle size from 5 microns to 0.3 microns. These reinforcement particles are dispersed in the matrix.

  • Aluminium-lithium alloy
    Patent number: 6485583
    Abstract: A dispersion strengthened mechanically alloyed aluminium based alloy is provided which is prepared by mechanical alloying and is characterized by improved isotropic strength, fracture toughness and corrosion resistance. The alloy system contains by weight 1.2 to 1.6% lithium, 4.0 to 6.0% magnesium, 0.15 to 0.7% carbon, up to 1% oxygen and up to 2.0% in total of one or more grain controlling elements to provide microstructural optimization and control, the balance aluminium save for incidental impurities.

  • Preparation of composites
    Patent number: 4749545
    Abstract: This invention relates to metal matrix composites containing at least 40% v/v of a hard material such as SiC and a matrix of aluminium, magnesium or alloys of either. The invention also covers a method of making such composites by ball milling powders of the respective components. Other mixing techniques do not enable such a high proportion of hard material to be incorporated into the composite. The composites are useful to produce components resistant to wear.
