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 (3) is placed into a crucible (2), 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 (5) 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： The present invention broadly relates to novel aluminum nitride matrix ceramic composite bodies for use as refractory materials and methods for making the same. The refractory materials are useful in environments which are corrosive, erosive, abrasive and/or which generate thermal shock. Such environments include furnaces, and associated apparatus which house or contact molten masses including, for example, molten metals, molten glasses, etc. The preferred method for making the aluminum nitride matrix ceramic composites comprises a directed oxidation of molten metal.

摘要： The present invention relates to a novel process for removal of at least a portion of at least one metallic component of a metallic constituent from a fiber reinforced ceramic matrix composite body. Particularly, by providing at least one of an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere to be in communication with a permeable mass, which contacts at least a portion of a composite body, said metallic component of the composite body, when made molten, is caused to spontaneously infiltrate the permeable mass. Such spontaneous infiltration occurs without the requirement for the application of any pressure or vacuum.
