    摘要: This invention relates generally to a novel method of manufacturing a composite body. More particularly, the present invention relates to a method for modifying the resultant properties of a composite body, by, for example, minimizing the amount of porosity present in the composite body. Moreover, additives, whether used alone or in combination, (1) can be admixed with the permeable mass, (2) can be mixed or alloyed with the parent metal, (3) can be placed at an interface between the parent metal and the preform or mass of filler material, (4) or any combination of the aforementioned methods, to modify properties of the resultant composite body. Particularly, additives such as VC, NbC, WC, W.sub.2 B.sub.5, TaC, ZrC, ZrB.sub.2, SiB.sub.6, SiC, MgO, Al.sub.2 O.sub.3, ZrO.sub.2, CeO.sub.2, Y.sub.2 O.sub.3, La.sub.2 O.sub.3, MgAl.sub.2 O.sub.4, HfO.sub.2, ZrSiO.sub.4, Yb.sub.2 O.sub.3 and Mo.sub.2 B.sub.5 can be combined with the permeable mass in an amount of about 5-50 percent by weight, prior to reactively infiltrating the permeable mass. Moreover, an additive may also include substantially pure elemental metals (e.g., Nb, Ti, Hf, V, Ta, Cr, Mo, Al, Cr, Si, Co and W) which may be provided by any of the methods discussed above herein.

    摘要: This invention relates generally to a novel method of manufacturing a composite body. More particularly, the present invention relates to a method for modifying the resultant properties of a composite body, by, for example, minimizing the amount of porosity present in the composite body. Additives such as TaC, ZrC, ZrB.sub.2, VC, NbC, WC, W.sub.2 B.sub.5 and/or MoO.sub.2 B.sub.5 can be combined with a boron carbide material which is thereafter reactively infiltrated by a parent metal. The composite body comprises one or more boron-containing compounds (e.g., a boride or a boride and a carbide) which is made by the reactive infiltration of molten parent metal into the boron carbide mass. Particular emphasis is placed upon modifying the properties of a ZrB.sub.2 -ZrC-Zr composite body. However, the methods disclosed in the application are believed to be generic to a number of parent metals and preform materials.

    摘要: This invention relates generally to a novel method of preparing self-supporting bodies, and novel products made thereby. In its more specific aspects, this invention relates to a method for producing self-supporting bodies comprising one or more boron-containing compounds (e.g., a boride or a boride and a carbide, etc.) by reactive infiltration of molten parent metal into a preform comprising boron carbide or a boron donor material combined with a carbon donor material and, optionally, one or more inert fillers, to form the body. Specifically, a boron carbide material or combination of a boron donor material and a carbon donor material, and in either case, optionally, one or more inert fillers, are sedimentation cast, spray coated, tapped, slip cast, pressed, etc., onto or into a body and into a particular desired shape.
