    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: The present invention relates to a novel method for forming a metal matrix composite body, and products produced thereby. Particularly, a permeable mass of filler material is formed into a preform (22) the preform (22) having at least a portion thereof which contains a cavity (30). An infiltration enhancer and/or an infiltration enhancer pre­cursor and/or an infiltrating atmosphere are also in com­munication with the preform (22) at least at some point during the process, which permits molten matrix metal (20) to spontaneously infiltrate the preform (22) when the pre­form (22) is placed into molten matrix metal (20). An in­filtrating atmosphere is provided in communication in the cavity (30) in the preform (22) for at least a portion of the process and molten matrix metal (20) is contacted with an exterior portion of the preform (22) such that molten matrix metal (20) will spontaneously infiltrate the preform (22) from an exterior surface thereof toward the cavity (30).

    Abstract: The present invention relates to a novel process for forming macrocomposite bodies. Particularly, a suitable matrix metal (33), typi­cally in a molten state, is in contact with a suitable mass of filler material or preform (31) located adjacent to, or in contact with, at least one second material 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 mass of filler material or preform (31) and/or impermeable container (32), thereby causing molten matrix metal (33) to infiltrate the mass of filler mate­rial or preform (31) 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 (33) infiltrates the mass of filler material or preform (31) to such an extent that the molten matrix metal (33) contacts at least a portion of the at least one second material. Upon cooling the matrix metal (33) to a temperature below the melting point of the ma­trix metal, a macrocomposite body is formed comprising a metal matrix composite body bonded to at least a portion of the at least one se­cond material.

    Abstract: The present invention relates to a novel method for forming metal matrix composite bodies. Particularly, a per­meable mass of filler material is formed into a preform (3). The preform material (3) can then be placed onto the surface of or into a matrix metal alloy (4), whereupon the matrix metal alloy (4) spontaneously infiltrates the pre­form (3). After substantial complete infiltration of the preform (3), the preform (3) begins to at least partially sink into the matrix metal alloy supply. The matrix metal (4) which has infiltrated the preform (3) is then allowed to cool, thus forming a metal matrix composite body (6).
