    Abstract: The present invention relates to a novel process for forming metal matrix composite bodies. Particularly, a suitable matrix metal (33), typically in a molten state, is in contact with a suitable filler mate­rial (31) or preform in the presence of a suitable reactive atmosphere in an impermeable container (32), at least at some point during the process, which permits a reaction to occur between the reactive atmos­phere and the molten matrix metal (33) and /or filler material (31) or preform and/or impermeable container (32), thereby causing molten matrix metal (33) to infiltrate the filler material (31) or preform due to, at least in part, the creation of a self-generated vacuum. Such self-genera­ted vacuum infiltration occurs without the application of any external pressure or vacuum.

    Abstract: Self-supporting bodies are produced by reactive in­filtration of a parent metal (10) into a boron nitride material (12) typically resulting in a body comprising a boron-containing compound, a nitrogen-containing compound and metal. The mass to be infiltrated may contain one or more inert fillers admixed with the boron nitride (12), to produce a composite by reactive infiltration, which com­posite comprises a matrix which embeds the filler material. The matrix, in a composite body containing filler material, comprises one or more of metal, a boron-containing com­pound and a nitrogen-containing compound. The relative amounts of reactants and process conditions may be altered or controlled to yield a body containing varying volume percents of ceramic, metal and/or porosity. The mass to be infiltrated can be contained within a refractory vessel having a venting means included therein.

    Abstract: Self-supporting bodies are produced by reactive in­filtration of a parent metal (10) into a boron donor ma­terial and a carbon donor material.

    Abstract: The present invention relates to a novel method for forming metal matrix composite bodies and the novel pro­ducts produced therefrom. A negative shape or cavity, which is complementary to the desired metal matrix composite body to be produced, is first formed. The formed cavity is thereafter filled with a permeable mass of filler material (7). Molten matrix metal (8) is then induced to sponta­neously infiltrate the filled cavity. Particularly, an in­filtration enhancer and/or an infiltration enhancer precur­sor and/or an infiltrating atmosphere are also in communi­cation with the filler material (7), at least at some point during the process, which permits the matrix metal (8) when made molten, to spontaneously infiltrate the permeable mass of filler material (7), which at some point during the processing, may become self-supporting. In a preferred em­bodiment, cavities can be produced by a process which is similar to the so-called lost-wax process.
