  • Wrought aluminum eutectic composites
    Patent number: 4992110
    Abstract: A method is provided for producing a wrought aluminum eutectic composite characterized by improved physical properties. The method resides in forming a casting of an aluminum alloy characterized metallographically by the presence of a eutectic structure, and then heat treating the casting at a temperature related to the eutectic-forming temperature of said alloy casting, that is just below its incipient melting point. The heat treatment is continued for a time at least sufficient to convert the morphology of the eutectic to dispersed fine particles of reinforcing phase(s), following which the alloy is physically worked to reduce the cross section thereof and provide a wrought aluminum eutectic composite characterized by improved physical properties.

  • Production of aluminum-SiC composite using sodium tetrasborate as an addition agent
    Patent number: 4713111
    Abstract: Reinforced composite aluminum-matrix articles containing silicon carbide fibers or particles, are produced by a casting process wherein the silicon carbide fibers or particles are mixed with dehydrated sodium tetraborate and mixed with molten aluminum or aluminum alloy whereby wetting of the reinforcing material and ready dispersal thereof in the aluminum matrix alloy is facilitated.
