    Abstract: The present invention relates to a novel method for forming metal matrix composite bodies and novel products produced by the method. Particularly, a permeable mass of filler material or a preform (1) has included therein at least some matrix metal powder. Moreover, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with the filler material or a preform (1), at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform (1). The presence of powdered matrix metal in the preform (1) or filler material reduces the relative volume fraction of filler material to matrix metal.

    Abstract: The present invention relates to the formation of a metal matrix composite body by a spontaneous infiltration technique. Particularly, an infiltration enhancer and/or infiltration enhancer precursor can be positioned at least partially between or at an interface between a matrix metal (2) and a filler material (3) (or preform) which is to be infiltrated by molten matrix metal (2). Moreover, at least at some point during the process, an infiltrating atmosphere may be in communication with the filler material or preform (3) and/or matrix metal (2).

    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.
