摘要： A cutting insert of a sintered carbonitride alloy and with a complicated geometry, the insert having improved efficiency. This is obtained by giving the powder non-uniform compaction during pressing of the powder into a press-body so that the ultimate working edges will have a higher relative density than the surrounding, more "supporting" material in the press-body. By these means are often obtained surface defects in the form of cracks because of dissolved strains during the sintering.

摘要： A dense cermet article including about 80-95% by volume of a granular hard phase and about 5-20% by volume of a metal phase. The granular hard phase consists essentially of a ceramic material selected from the hard refractory carbides, nitrides, carbonitrides, oxycarbides, oxynitrides, carboxynitrides, and borides of titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, boron, and mixtures thereof. The metal phase consists essentially of a combination of nickel and aluminum having a weight ratio of nickel to aluminum of from about 90:10 to about 70:30 and 0-5% by weight of an additive selected from the group consisting of titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, cobalt, boron, or carbon, or combinations thereof. In the preferred metal phase, an amount of about 15-80% by volume of the metal phase component exhibits a Ni.sub.3 Al ordered crystal structure. The article may be produced by presintering the hard phase - metal phase component mixture in a vacuum or inert atmosphere at about 1475.degree.-1675.degree. C., then densifying by hot isostatic pressing at a temperature of about 1575.degree.-1675.degree. C., in an inert atmosphere, and at about 34-207 MPa pressure. Limiting the presintering temperature to 1475.degree.-1575.degree. C. and keeping the presintering temperature at least 50.degree. C. below the not pressing temperature produces an article of gradated hardness, harder at the surface than at the core.

摘要： High pressure sintered bodies of polycrystalline diamond or carbide ceramics are rendered more resistant to cracking by establishing dispersed, localized "stress centers" of submicron size particles of lonsdaleite, diamond, or other form of metastable, high density carbon which has the capability of transforming crystallographically to graphite in situ in the body. When an incipient crack in the body approaches entrapped metastable particles along its path, the crack promotes or permits transformation of the metastable particles to graphite particles, with concomitant increase in their size, thereby resisting further propagation of the crack.

摘要： Dense, strong, composite materials are produced from mixtures of silicon and silicon carbide. The composite materials are characterized by a mixture of finely-divided silicon carbide in a substantially continuous matrix of silicon. The composite materials contain from about 40 to about 60 percent by volume silicon carbide and from about 60 to about 40 percent by volume silicon. The composite materials are produced by initially producing a finely-divided silicon carbide starting component and forming the component into a green body of the desired shape. The green body is subsequently impregnated with molten silicon in the absence of any substantial amount of carbon. Suitably, a thermoplastic resin binder may be added to the silicon carbide starting material to aid in forming the green body. The impregnation step may be carried out by surrounding the green body with finely-divided silicon metal and heating the covered body to a temperature above the melting point of silicon. The composite materials described have flexural strength of over about 90,000 psi at 1100.degree. C., elastic modulus of about 38 million psi at room temperature, are essentially non-porus and have densities ranging from about 2.6 to about 2.8 g/cc.

摘要： A microcomposite material having a matrix of a titanium-base alloy, the material further including about 10-80% by weight TiC substantially uniformly dispersed in the matrix. Several methods of cladding a macrocomposite structure including pressing quantities of a matrix material and a microcomposite material composed of the matrix material and a compatible stiffener material into layers to form a multi-layered compact and sintering the multi-layered compact to form an integral metallurgical bond between the layers of the compact with diffusion but essentially no composition gradient between the layers. A multi-layered macrocomposite article composed of an alloy layer of a matrix material and a layer of a microcomposite material composed of the matrix material and a compatible stiffener material bonded together at the interface region between the layers, the interface region being essentially free of a composition gradient.
