摘要： The present invention relates to modifying the properties of a metal matrix composite body by a post formation process treatment and/or a substantially contiguous modification treatment. The post formation process treatment may be applicable to a variety of metal matrix composite bodies produced by various techniques, and is particularly applicable to modifying the properties of a metal matrix composite body produced by a spontaneous infiltration technique. The substantially contiguous modification process may also be used primarily in conjunction with metal matrix composite bodies produced according to a spontaneous infiltration technique. Particularly, at least a portion of the matrix metal of the metal matrix composite body and/or the filler material of the metal matrix composite body is modified or altered during and/or after the formation process.

摘要： The present invention relates to a novel method for forming cast metal matrix composite bodies. In particular, the present invention relates to a novel method for forming or recycling metal matrix composite bodies so as to render such bodies in a condition for casting or recasting as a cast metal matrix composite body. Specifically, a scrap metal matrix composite body and preferably a scrap cast metal matrix composite body is placed into a crucible, optionally along with unreinforced matrix metal and/or virgin metal matrix composite material. Whether the scrap and/or virgin materials are placed into the crucible in solid or molten form, the contents of the crucible are ultimately rendered molten to form a composite melt. A means for applying high shearing rates to the composite melt, such as an impeller rotating at high speed is immersed into the composite melt and the composite melt is sheared for a time sufficient to comminute any entrained inclusions such as entrapped oxide skins to a size at which such comminuted inclusions are substantially ameliorated in terms of their effect on the fluidity of the composite melt and the mechanical properties of the subsequent cast metal matrix composite bodies. Upon conclusion of the high intensity shearing process, the high power shearing apparatus is removed from the composite melt and the composite melt is cast using appropriate techniques for casting metal matrix composite material.

摘要： This invention relates generally to a novel directed metal oxidation process which is utilized to produce self-supporting bodies. In some of the more specific aspects of the invention, a parent metal (e.g., a parent metal vapor) is induced to react with at least one solid oxidant-containing material to result in the directed growth of a reaction product which is formed from a reaction between the parent metal and the solid oxidant-containing material. The inventive process can be utilized to form bodies having substantially homogeneous compositions, graded compositions, and macrocomposite bodies.In a preferred embodiment, a substance comprising a filler material and a solid oxidant, preferably an admixture of particulates, is coated onto at least a portion of the solid oxidant-containing material. Such a technique is particularly advantageous for forming relatively thick reaction product layers which might not otherwise develop to the desired thickness using the original "directed growth" embodiment. In a particularly preferred embodiment, the solid oxidant and the solid oxidant-containing material have the same chemical composition, and the filler material and the reaction product have the same chemical composition.

The inventive process can be utilized to form bodies having substantially homogeneous compositions, graded compositions, and macrocomposite bodies. In a preferred embodiment, the reaction product may be chemically modified or a different reaction product may be coated thereon. Specifically, once a first reaction product is formed on a solid oxidant-containing material, the formed body may be exposed to a vapor-phase parent metal different from the first parent metal. Alternatively, the formed body may be exposed to a vapor-phase oxidant having a different chemical composition then the solid oxidant-containing material. Still further, a non-stoichiometric reaction product deficient in the oxidant component may be made more stoichiometric by heating the self-supporting body in the absence of reaction product growth conditions at a temperature and for a time sufficient to effect diffusion of additional oxidant from the solid oxidant-containing material into the sub-stoichiometric reaction product, thereby increasing its stoichiometry.
