    Abstract: A ceramic-reinforced aluminum matrix composite is formed by contacting a molten aluminum-magnesium alloy with a permeable mass of ceramic material in the presence of a gas comprising from about 10 to 100% nitrogen, by volume, balance non-oxidizing gas, e.g., hydrogen or argon. Under these conditions, the molten alloy spontaneously infiltrates the ceramic mass under normal atmospheric pressures. A solid body of the alloy can be placed adjacent a permeable bedding of ceramic material, and brought to the molten state, preferably to at least about 700°C, in order to form the aluminum matrix composite by infiltration. In addition to magnesium, auxiliary alloying elements may be employed with aluminum. The resulting composite products may contain a discontinuous aluminum nitride phase in the aluminum matrix and/or an aluminum nitride external surface layer.

    Abstract: The present invention relates to modifying the properties of a metal matrix composite body by a post formation process treatment and/or a substantially contiguous modification treatment. The post formation process treatment may be applicable to a variety of metal matrix composite bodies produced by various techniques, and is particularly applicable to modifying the properties of a metal matrix composite body produced by a spontaneous infiltration technique. The substantially contiguous modification process may also be used primarily in conjunction with metal matrix composite bodies produced according to a spontaneous infiltration technique. Particularly, at least a portion of the matrix metal of the metal matrix composite body and/or the filler material of the metal matrix composite body is modified or altered during and/or after the formation process.

    Abstract: A complex oxidation reaction product of two or more metals in an oxidized state is formed by positioning a suitable precursor metal (1) adjacent to a permeable mass (2) of a metal-containing compound in an oxidizing atmosphere and heating the assembly to form a body of molten precursor metal. The molten metal infiltrates the permeable mass (2) and reacts therewith and with the oxidizing atmosphere to form a complex oxidation reaction product. Methods for determining the shape of the resulting article are described. The disclosed methods can be used to form superconducting perovskites.

    Abstract: The present invention relates to the formation of me­tal matrix composite bodies by a spontaneous infiltration technique, and novel metal matrix composite bodies produced according to the method. An ingot (4) of matrix metal is surrounded by a permeable mass of filler material (5). An infiltration enhancer and/or an infiltration enhancer pre­cursor and/or an infiltrating atmosphere are also in commu­nication with the filler material (5), at least at some point during the process, which permit the shaped ingot (4) of matrix metal, when made molten, to spontaneously infil­trate the surrounding permeable mass of filler material (5). After the spontaneous infiltration, a metal matrix composite body is produced having therein a cavity which substantially corresponds in shape to the original ingot (4) of matrix metal.
