摘要： An abrasive composite particle comprising a cubic abrasive core particle encapsulated within a deposit of hexagonal metallurgical bond forming material comprising at least about 50 volume percent rhenium, ruthenium, osmium or mixtures thereof. The metallurgical bonds serve to retain the core particle in a matrix/binder very strongly. Metallurgical bonds are formed by the encapsulating material taking into solution, at the interface with the cubic abrasive core particle, some element or compound from the abrasive particle such as, for example, carbon or cubic boron nitride, from the core particle. Chemical bonds are not formed between the abrasive particle and the deposit. Suitable abrasive core particles include diamond, cubic carbides, cubic borides, cubic nitrides, cubic oxides, and the like. Conventional fabrication procedures such as chemical vapor deposition are employed to form the metallurgical bond forming deposit on the core particle. The composite abrasive particles are useful in forming articles according to conventional powdered metal processing operations. The articles so formed are useful for their hardness as well as their abrasiveness.

摘要： A muzzle flash and blast suppressor comprising a body of reticulated refractory foam generally surrounding the projectile path adjacent the muzzle of a device. One side of the body of foam is exposed to the pressure within the projectile path just behind the projectile, and the other side is exposed to the unconfined ambient pressure. The foam is required to be possessed of sufficient structural strength to permit its exterior side to be exposed without confinement to the ambient environment. Hot exhaust gasses flowing laterally of the projectile path pass through the body from the high to the low pressure side. In such passage the gasses are cooled by expansion and by contact with the interstices of the body. Debris is filtered out and the pressure is substantially reduced. Typically, the refractory foam has from approximately 30 to 100 pores per inch and is from approximately 90 to 50 percent void volume.

摘要： A composite body that is spall resistant and comprises a substantially discontinuous cermet phase in a substantially continuous metal rich matrix phase. The composite body is typically bonded to a substrate to form a hardfacing on the substrate. The composite body exhibits ductile phase toughening with a strain to failure of at least about 2 percent, a modulus of elasticity of less than about 46 million pounds per square inch, and a density of less than about 7 grams per cubic centimeter. The metal rich matrix phase between the ceramic rich regions in the composite body has an average minimum span of about 0.5 to 8 microns to allow ductility in the composite body. The composite body has a Vicker's hardness number of greater than approximately 650. The discontinuous cermet phase is in the form of ceramic rich regions embedded within the composite body, and it includes ceramic particles and a cermet binder. The ceramic particles having a Moh's hardness of at least approximately 7.5, a modulus of elasticity of less than approximately 46 million pounds per square inch, and an average particle size of from about 0.1 to 10 microns. The ceramic rich regions exhibit high hardness as compared with the matrix phase.

摘要： A heterogeneous body having ceramic rich cermet regions in a more ductile metal matrix. The heterogeneous bodies are formed by thermal spray operations on metal substrates. The thermal spray operations apply heat to a cermet powder and project it onto a solid substrate. The cermet powder is composed of complex composite particles in which a complex ceramic-metallic core particle is coated with a matrix precursor. The cermet regions are generally comprised of complex ceramic-metallic composites that correspond approximately to the core particles. The cermet regions are approximately lenticular shaped with an average width that is at least approximately twice the average thickness. The cermet regions are imbedded within the matrix phase and generally isolated from one another. They have obverse and reverse surfaces. The matrix phase is formed from the matrix precursor coating on the core particles. The amount of heat applied during the formation of the heterogeneous body is controlled so that the core particles soften but do not become so fluid that they disperse throughout the matrix phase. The force of the impact on the surface of the substrate tends to flatten them. The flattened cermet regions tend to be approximately aligned with one another in the body.

摘要： A process for producing a binder phase free fine grained refractory metal compact at temperatures that are less than about 80 percent of the melting point of the refractory metal. A refractory metal is mixed with a metallic reagent to produce a mixture with a low melting point, and formed into a preform. The metallic reagent has limited solubility in the solid phase refractory metal. The refractory metal-metallic reagent mixture forms a liquid phase at the boundaries of the refractory metal grains. The metallic reagent diffuses into the boundaries of the refractory grains leaving a solid refractory-reagent phase at the boundaries between the grains. As heating continues at less than about 80 percent of the melting point of the refractory metal, consolidation takes place with minimum grain growth until the solid refractory-reagent phase substantially disappears and a refractory metal compact without a binder phase is recovered. If the refractory metal-metallic reagent preform is compacted to less than about 50 percent of theoretical density, it is possible to recover a microporous compact. At higher compaction rates substantially fully dense compacts are recovered. It is not necessary to apply pressure during the sintering phase.

摘要： Composite layers are formed on substrates, particularly heat sensitive substrates. A uniform composite mixture is prepared from powdered nanoscale ceramic phase particulates and a particulate matrix phase precursor that contains a fusible matrix former. The composite mixture is applied to the substrate surface where it forms a composite mixture layer that is thin relative to the substrate. The composite mixture layer is subjected to a rapid high flux heating pulse of energy to fluidize the fusible matrix former, followed by a rapid quenching step that occurs at least in part because of heat transfer to the substrate, but without significantly damaging the overall temper properties of the substrate. The nanoscale ceramic phase is present in the composite layer in an amount that is greater than its percolation threshold, so the resulting fused composite layer does not tend to flow or sag while the matrix former is in the fluid state. Also, the grain size of the matrix is minimized by the presence of the nanoscale ceramic phase.

摘要： A method of forming dense articles from metal or metal alloy powders by friction forming. A self supporting shaped deposit of powder is formed on a substrate. Relative movement is established between the shaped deposit and a friction forming tool. The forming end of the friction tool is urged into compressive contact with the shaped deposit so as to generate an amount of heat sufficient to plasticize the deposit and thereby form a dense article. The steps may be repeated to built up the article to any pre-desired thickness. The substrate may be removed to establish a free standing coherent article, or the article may be left tightly bonded to the substrate. The article is very uniform in both thickness and composition, and enjoys substantially full density and a very fine microstructure.
