摘要： Fibers for diamond-impregnated cutting tools and their associated methods for manufacture and use are described. A matrix is formed that contains fibers made from carbon, glass, ceramic, polymer, and the like. The matrix is then sintered to form a cutting portion of a drill bit. The type and concentration of the fibers can be modified to control the tensile strength and the erosion rate of the matrix to optimize the cutting performance of the tools. Additionally, the fibers may be added to the cutting section to weaken the structure and allow higher modulus binders to be used for the cutting tools at a lower cost, allowing the amount of fibers to be tailored to retain the diamonds in the cutting portion for the desired amount. As the cutting portion erodes, the fibers may also increase the lubricity at the face of the cutting portion.

摘要： A method of manufacturing an axisymmetric component made of a composite material having a metallic matrix is described in which at least one ceramic fiber and at least one wire of the metal which is to constitute the matrix are wound simultaneously side by side to form a number of layers on a suitably shaped mandrel and in such a manner as to ensure absence of contact between the fiber turns of each individual layer and between the fiber turns of adjacent layers, and the formed layers are subsequently subjected to hot isostatic compaction. The ceramic fiber may be of the silicon carbide type and the metal wire forming the matrix may be of titanium or titanium-alloy.

摘要： A composite structural ceramic article and method of fabrication thereof. The article of the invention is specifically designed for use in high temperature, corrosive and erosive environments such as those found in heat engines, heat exchangers, stationary power equipments and industrial process equipments. The article comprises a porous carbon fibrous substrate or other suitable high temperature fibrous substrate which may include: a pyrolytic carbon or appropriate chemical vapor deposited sheath formed about each fiber of the substrate; a chemically vapor deposited metallic carbide, oxide, boride or nitride coating over the coated fibers of the substrate; and an impermeable metallic carbide, oxide, boride or nitride outer protective layer formed about the entire periphery of the coated substrate. In accordance with the method of the invention, the metallic coating is applied to the fibers in such a manner such that internal porosity of the article is precisely controlled and a flaw resistant, tough, non-catastrophic failing structural ceramic body is formed.

摘要： A method of forming bulk metallic glass engineering materials, and more particularly a method for forming coarsening microstructures within said engineering materials is provided. Specifically, the method forms ‘designed composites’ by introducing ‘soft’ elastic/plastic inhomogeneities in a metallic glass matrix to initiate local shear banding around the inhomogeneity, and matching of microstructural length scales (for example, L and S) to the characteristic length scale RP (for plastic shielding of an opening crack tip) to limit shear band extension, suppress shear band opening, and avoid crack development.
