    Abstract: The present invention relates to novel process for forming net or near net-shape metal matrix composite bodies. Particularly, a molten matrix metal (13) is in contact with a filler material or a preform (11) in the presence of a reactive atmosphere, at least at some point during the process, which permits molten matrix metal (13) to react, at least partially or substantially completely, with the re­active atmosphere, thereby causing molten matrix metal (13) to infil­trate the filler material or preform (11) 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. The molten matrix metal (13) infiltrates the filler material (11) up to at least a portion of a provided barrier means.

    Abstract: An aluminum metal matrix composite comprises an aluminum metal matrix embedding a second filler (2), such as a ceramic second filler, and is formed by contacting, for example, a molten aluminum metal (20) with a permeable mass of second filler (22) within a ceramic impervious mold (12) formed by growing a polycrystalline oxidation reaction product into a first filler. By hermetically sealing the second filler (22) within the mold (12) with a body of molten aluminum metal (20), the latter spontaneously infiltrates the mass of second filler (22) at moderate temperatures, e.g. about 900°C, without need of any other infiltration expedients. The molten mass containing the infiltrated ceramic filler is solidified to provide the metal matrix composite which may be recovered from the mold (12). Optionally, the solidification is carried out under bonding conditions including maintaining the solidi­fying material in direct contact with the ceramic mold, to provide the metal matrix composite joined to the mold, or a part thereof, as a structural component.

    Abstract: This invention relates generally to a novel method of preparing self-supporting bodies, and novel products made thereby. In its more specific aspects, this invention relates to a method for producing self-supporting bodies comprising one or more boron-containing compounds, e.g., a boride or a boride and a carbide, by reactive infiltration of molten pa­rent metal (10) into a preform (20) comprising boron carbide or a boron donor material combined with a carbon donor mate­rial and, optionally, one or more inert fillers, to form the body. Specifically, a boron carbide material or combination of a boron donor material and a carbon donor material, and in either case, optionally, one or more inert fillers, are se­dimentation cast, slip cast or pressed onto or into a body and into a particular desired shape.

    Abstract: A method is provided for producing a self-supporting ceramic composite body having a plurality of spaced apart wall members, each wall member having a bounded cross-­section for defining substantially continuous, fluid passageways. The wall members generally inversely replicate in opposed directios the geometry of a positive pattern. Each of the wall members, which are axially aligned, comprises a ceramic matrix having a filler embedded therein, and is obtained by the oxidation reaction of a parent metal to form a polycrystalline material which consists essentially of the oxidation reaction product of the parent metal with an oxidant and, optionally, one or more metals, e.g. nonoxidized constituents of the parent metal.
