Abstract: The specification and drawings describe and show an embodiment of and method of forming a liquid flow through heat exchanger structure cast in a metal matrix composite. The composite comprises a preform reinforcement material infiltrated with molten metal. The composite reinforcement material is injection molded around the heat exchanger structure allowing for intimate contact between the composite and structure. The composite formed has a specific coefficient of thermal expansion to match an active heat-generating device mounted thereon. The present invention allows for enhanced thermal and mechanical properties by eliminating voids or gaps at the composite to heat exchanger structure interface, these voids or gaps being present in prior art fabrication methods or induced by usage due to thermal cycling of prior art composites.

Abstract: A free machining aluminum alloy contains an effective amount of one or more high melting point constituents that provide enhanced machining capability. The high melting point constituents occupy from about 0.1 to about 3.0 volume percent of the aluminum alloy. The constituents can be any material that is essentially insoluble in the aluminum alloy matrix so as to form a discontinuity and one that will resist deformation during machining to enhance the formation of voids between the matrix and the free machining constituents. The constituents include elements, nitrides, oxides, borides, carbides, silicides, aluminides and combinations thereof that have a high melting point and high strength and low solubility in aluminum at the elevated temperature so that the constituents resist deformation during the machining operation. The free machining aluminum alloy can be formed as a workpiece and subjected to any machining operation.

Abstract: A mass of graphite is placed into a case, and the case is put into a furnace (step S301). The space in the furnace is heated to produce a porous sintered body of graphite (step S302). Thereafter, the case with the porous sintered body contained therein is removed from the furnace, and put into a cavity in a press (step S303). Then, a molten mass of a metal is poured into the case (step S304), and a punch is inserted into the cavity to press the molten metal into the porous sintered body in the case (step S305).

Abstract: A rapid tooling method is provided for molding metal particles, ceramic particles or mixtures thereof directly from patterns comprising a meltable, soluble or decomposable substance and preferably formed by rapid prototyping technology, as well as particle compositions therefor. The method comprises mixing at least about 95% by weight sinterable metal particles, sinterable ceramic particles or mixtures thereof with at least about 0.5 wt. % to about 5.0 wt. % binder to form a powder mixture; casting the mixture around a pattern; applying pressure sufficient to compact the mixture to form a preform; removing the pattern; and heating the preform at a sintering temperature sufficient to sinter the particles and form a molded article. The pattern may be removed by either melting, dissolving or decomposing, and the sintering process preferably includes two stages which are performed simultaneously with the infiltration of metal, whereby which both shrinkage and distortion of molded article can be reduced or eliminated.

Abstract: A method for mixing particles in a liquid or semi-liquid medium, such as ceramic reinforcing particles in a molten metal or metal alloy matrix for the production of stir-cast metal matrix composite (MMC) materials. The particles can be introduced under the surface of the matrix by feeding the particles through the inner passage of a rotatable hollow impeller tube. The impeller tube is terminated at its lower end by an impeller head that includes teeth positioned proximate to an impeller base. The particles enter the matrix through a shear region in and around the volume between the impeller base and the impeller head. The rotating impeller and the high shear force thereby created wet the particles in the composite matrix and effect homogenization of the composite matrix. The present invention may be practiced either under vacuum or atmospheric pressure.

Abstract: A method of adding boron to a tungsten, or tantalum, containing titanium aluminide alloy to form a boride dispersion in the tungsten, or tantalum, containing titanium aluminide. A molten tungsten, or tantalum, containing titanium aluminide alloy is formed and tungsten, or tantalum, boride is added to the molten tungsten, or tantalum, containing titanium aluminide alloy to form a molten mixture. The molten mixture is cooled and solidified to form a tungsten, or tantalum, containing titanium aluminide alloy having a uniform dispersion of tungsten, or tantalum, boride particles substantially without the formation of clusters of tungsten, or tantalum, boride. The titanium aluminide alloy comprises between 0.5 at % and 2.0 at % boron.
