Abstract: A consolidated complex shaped article having a density of at least about 95 percent of theoretical density is prepared by placing a plurality of separate bodies in an arrangement, such that each separate body is in contact with at least one other separate body to form an aggregate body and wherein at least one of the separate bodies is essentially dense. The material of each separate body is comprised of a ceramic, a cermet or a metal. The aggregate body is then consolidated at a consolidating temperature, superatmospheric pressure and time at temperature and time at superatmospheric pressure sufficient to form a consolidated shaped article. In consolidating the aggregate body, the consolidating temperature is a temperature that fails to form a liquid within at least one separate body and the superatmospheric temperature is applied for at least a portion of the time at the consolidating temperature.

Abstract: Thermoformable films that contain a blend and/or composite structure containing an ethylene/vinyl or vinylidene aromatic polymer or an alpha-olefin/vinyl or vinylidene aromatic polymer, such as an ethylene/styrene interpolymer, a vinyl or vinylidene aromatic homo- or copolymer, such as polystyrene, and, optionally, an alpha-olefin homo- or copolymer serve as effective carrier layers for heat transfer foils.

Abstract: A cemented tungsten carbide body having a transition metal binder phase selected from the group consisting of iron, nickel and cobalt is formed, wherein the WC grains have an average WC grain size of at most about 0.5 micrometer in diameter and a maximum WC grain size of at most about 0.8 micrometer in diameter. Also, about 50 percent by volume of the WC grains in the body are angular grains and the body (1) contains an amount of the transition metal ranging from about 3 percent to about 18 percent by weight of the body, (2) is essentially free of grain growth inhibitors and (3) is essentially pore free.

Abstract: A multi-phase cemented ceramic article, method of making same, and the material thereof is disclosed which is useful for machining and forming of metals, including ferrous metals, titanium, aluminum and other metals. The article and its material preferably includes novel microstructures including platelets, a range of grain sizes which yields superior hardness and other characteristics, and a lower tungsten concentration within the binder phase than has been seen in the prior art. The preferred composition includes ultrafine WC, an ultrafine solid solution of (Ti, Ta, W)C, and a cobalt binder. Platelets are formed in-situ, eliminating the need to add them during manufacture for improving toughness.

Abstract: Densified refractory carbide and solid solution carbide materials that have an average grain size of less than 1.1 .mu.m, a density of at least 98% of theoretical may be prepared by any conventional densification procedure. Pressure densified tungsten carbide ceramic materials exhibit a simultaneous increase in Vickers hardness and a toughness (K.sub.IC) with decreasing average grain size.

Abstract: A powdered admixture of a boron, carbon, nitrogen or silicon derivative of a first metal is combined with a source of a second metal and, optionally, a source of a third metal or an iron-group metal, subjected to densification conditions (heat and pressure), partially reacted and converted to a hard, wear resistant material. The wear resistant material contains an amount of the first metal derivative as well as a material of varying stoichiometry which is the partial reaction product of components of the powdered admixture. The material may also contain residual, unreacted portions of components other than the first metal derivative. Articles formed from this material can be useful as, for example, nozzles in abrasive or nonabrasive waterjet cutting machines and various parts of wire drawing apparatus.

Abstract: A powdered admixture of a boron, carbon, nitrogen or silicon derivative of a first metal, e.g., tungsten carbide, and a source of a second metal, e.g., molybdenum subcarbide when the second metal is molybdenum, is, when subjected to densification conditions, partially reacted and converted to a hard, wear resistant material. Such a material, formed from an admixture of tungsten carbide and molybdenum subcarbide, contains tungsten monocarbide and at least one mixed tungsten/molybdenum carbide. This material has a Vickers hardness of at least about 2200 kg/mm.sup.2 measured using a 1 kg load. Articles formed from this material can be useful as, for example, nozzles in abrasive or nonabrasive waterjet cutting machines and various parts of wire drawing apparatus.
