    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.

    摘要: This invention relates generally to a novel method for forming a self-supporting body. Specifically, the formed self-supporting body has a higher volume percent of metallic constituent relative to a body formed by similar techniques. A first porous self-supporting body is formed by reactively infiltrating a molten parent metal into a bed or mass containing a boron donor material and a carbon donor material (e.g., boron carbide) and/or a boron donor material and a nitrogen material (e.g., boron nitride) and, optionally, one or more inert fillers. Additionally, powdered parent metal may be admixed with a mass to be reactively infiltrated to form additional porosity therein. The porous self-supporting body which is formed by the reactive infiltration process according to this invention should contain at least some interconnected porosity which is capable of being filled in a subsequent step with additional metal, thus increasing the volume percent of parent metal in the body at the expense of porosity.

    摘要: A composite adhesive featuring a matrix phase that includes a cyanate ester and a filler or reinforcement phase that includes a plurality of bodies of at least one material comprising a high shear strength and/or high modulus material. Preferably, the filler also possesses at least one of high thermal conductivity and low coefficient of thermal expansion. Unlike certain commercially available cyanate esters, those of the instant invention substantially maintain or even increase in strength upon addition of the filler to the system. The instant composite adhesives may also display reduced coefficients of moisture expansion relative to the unfilled or “neat” resin. Such a composite adhesive is extremely useful for joining articles where high strength and minimal swelling in moist environments are required, such as in the precision equipment industry. In particular, the instant adhesives find great utility in joining components for semiconductor fabrication equipment, such as those that support the optics in a lithography machine.
