Abstract: The present invention relates to a novel process for forming net or near net-shape metal matrix composite bodies. Particularly, a molten matrix metal is in contact with a filler material or a preform in the presence of a reactive atmosphere, at least at some point during the process, which permits molten matrix metal to react, at least partially or substantially completely, with the reactive atmosphere, thereby causing molten matrix metal to infiltrate the filler material or preform due to the creation of a self-generated vacuum. Forming a glassy seal on the reaction system, the self-generated vacuum infiltration occurs without the application of any external pressure or vacuum. The molten matrix metal infiltrates the filler material up to at least a portion of a provided barrier means.

Abstract: Premixed material was formed by mixing alumina fiber and/or carbon fiber, titanium oxide particle and aluminum powder and was sintered to bind alumina (aluminum oxide), produced by the oxidation-reduction reaction of titanium oxide particles and aluminum powder, and a titanium-nitrogen compound in a film on the surface of alumina fiber and/or carbon fiber, and to form preform for the composite material. The composite material had high strength because preform for the composite material produced by the manufacturing method had excellent strength and breathability, and occurrence of unfilled pore space in the composite material formed by impregnating hot solution of such as aluminum alloy was prevented.

Abstract: A cast article from an aluminum alloy has improved mechanical properties at elevated temperatures. The cast article has the following composition in weight percent: Silicon 6.0-25.0, Copper 5.0-8.0, Iron 0.05-1.2, Magnesium 0.5-1.5, Nickel 0.05-0.9, Manganese 0.05-1.2, Titanium 0.05-1.2, Zirconium 0.05-1.2, Vanadium 0.05-1.2, Zinc 0.05-0.9, Strontium 0.001-0.1, Phosphorus 0.001-0.1, and the balance is Aluminum, wherein the silicon-to-magnesium ratio is 10-25, and the copper-to-magnesium ratio is 4-15. The aluminum alloy contains a simultaneous dispersion of three types of Al3X compound particles (X=Ti, V, Zr) having a L12 crystal structure, and their lattice parameters are coherent to the aluminum matrix lattice. A process for producing this cast article is also disclosed, as well as a metal matrix composite, which includes the aluminum alloy serving as a matrix containing up to about 60% by volume of a secondary filler material.
