Abstract: Self-supporting bodies are produced by reactive in­filtration of a parent metal (10) into a boron carbide ma­terial (12) which may contain one or both of a boron donor material and a carbon donor material. The reactive infil­tration typically results in a composite comprising a boron-containing compound, a carbon-containing compound and residual metal, if desired. The mass to be infiltra­ted may contain one or more inert fillers admixed with the boron carbide material (12), boron-containing compound and/­or carbon-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, ratios of one ceramic to another and porosity.

Abstract: The present invention relates to a novel method for forming metal matrix composite bodies. A permeable mass of filler material (1) is spontaneously infiltrated by a mol­ten matrix metal (3). Particularly, an infiltration enhan­cer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with the filler material (1) at least at some point during the process, which permits molten matrix metal (3) to sponta­neously infiltrate the filler material (1). After infiltra­tion has been completed to a desired extent, additional matrix metal is added to that matrix metal (3) which has spontaneously infiltrated the filler material (1) to re­sult in a suspension of filler material (1) and matrix me­tal (3), said suspension having a lower volume fraction of filler relative to matrix metal. The matrix metal (3) then can be permitted to cool in situ or the mixture of matrix metal and filler material can be poured into a second con­tainer as a casting process to form a desired shape which corresponds to the second container. However, the formed suspension, whether cast immediately after being formed or cooling and thereafter heating and casting, can be pour cast into a desired shape.

Abstract: The present invention relates to a novel method for forming metal matrix composite bodies and novel metal matrix composite bodies produced thereby. Particularly, a polycry­stalline oxidation reaction product of a parent metal and an oxidant is first formed. The polycrystalline oxidation reaction product is thereafter comminuted into an appro­priately sized filler material (2) which can be placed into a suitable container (4) or formed into a preform. The fil­ler material or preform of comminuted polycrystalline oxi­dation reaction product (2) is thereafter placed into con­tact with a matrix metal alloy (1) in the presence of an infiltration enhancer, and/or an infiltration enhancer pre­cursor and/or an infiltrating atmosphere, at least at some point during the process, whereupon the matrix metal alloy (1) spontaneously infiltrates the filler material or pre­form. As a result of utilizing comminuted or crushed poly­crystalline oxidation reaction product, enhanced infiltra­tion (e.g., enhanced rate or amount) is achieved. Moreover, novel metal matrix composite bodies are produced.

Abstract: A net shaped ceramic-reinforced aluminum matrix composite is formed by forming a permeable mass of ceramic material (10) with a defined surface boundary having a barrier, and contacting a molten aluminum-magnesium alloy (20) with the permeable mass of ceramic material (10) in the pre­sence of a gas comprising from about 10 to 100 % nitrogen, by volume, balance nonoxidizing gas, e.g. hydrogen or argon. Under these conditions, the molten alloy (20) spontaneously infiltrates the ceramic mass under normal atmospheric pressures until it reaches the barrier. A solid body of the alloy (20) can be placed adjacent to a permeable bedding of ceramic material (10) having a barrier, and brought to the molten state, preferably to at least about 700°C, in order to form the net shape 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.

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.

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.
