摘要： A deformed ultra fine grain is comprised of a spherical body and a tail-like projection projecting from the surface of the spherical body. The tail-like projection exhibits a separating effect on the adjacent deformed ultra fine grains and therefore, aggregation of the ultra fine grains is avoided. Bulk quantities of the deformed ultra fine grains are produced by evaporating a metal by a plasma arc in a controlled atmosphere having a gas that combines with the material of the spherical body to form the tail-like projection.

摘要： Ultrafine amorphous metal particles which combine the properties of ultrafine particles with those of an amorphous alloy and a method for the production thereof are disclosed. The ultrafine amorphous metal particles are produced by a method which comprises discharging a plasma arc against a raw metal capable of forming a carbide in a reaction gas using an inert gas as a main component thereof and containing a hydrocarbon gas, and allowing the metal which has been consequently vaporized to contact the reaction gas which has been consequently converted into a plasma, thereby inducing formation of a solid solution of carbon atoms in the vaporized metal and quenching the solid solution in the reaction gas to confer an amorphous structure thereon. As the raw metal, at least one metal selected from the group consisting of Fe, Mo, Nb, Ta, Ti, Zr, Al, Si, and Cr is preferably used. By this method are obtained ultrafine amorphous metal particles which comprise the metal mentioned above, possess at least 50% by volume of an amorphous phase, and have particle diameters of not more than 500 nm.

摘要： Ultrafine particles of aluminum nitride having a morphologically anisotropic structure of columns, plates, or whiskers such that the ratio of thickness or width to length or the ratio of thickness to width or length of particle is not less than 1 are produced by thermally melting a binary alloy of metallic aluminum and a rare earth element in a nitriding atmosphere containing nitrogen. By this method are produced composite ultrafine particles which substantially comprise ultrafine particles of aluminum nitride having the morphologically anisotropic structure and ultrafine particles of the rare earth nitride which functions as a sintering auxiliary therefor. The composite ultrafine particles or an aggregate thereof are usable as a raw material for the production of a sintered article, a reinforcing material for various metal-based composite materials, a blast powder, and the like.

摘要： A structural member is produced using starting powder consisting of composite particulates each containing AlN grain within its surface covered by an Al layer of a single crystal structure, and Al alloy particulates of a single crystal structure, and then by sintering the Al layers of the composite particulates with the Al alloy particulates. The Al layers and the Al alloy particulates of the single crystal structure have no dislocation fault, crystal grain boundary. etc., produced therein, and for this reason, they have a low chemical activity. Therefore, the Al layers and the like have a characteristic that they are extremely difficult to oxidize. This ensures that the Al layers and the Al alloy particulates can be reliably sintered to achieve the densification of the resulting structural member.

By this method, ultrafine composite particles or a mixture comprising ultrafine whiskery or columnar aluminum nitride particles and ultrafine particles of the metal, the intermetallic compound of the metal with aluminum, and the nitride ceramic of the metal are produced. The ultrafine particles thus obtained find extensive utility as sintering materials and dispersion materials, for example.

摘要： Deposition of a hard film of Ti--Si--N composite material on a substrate is carried out by using a source of evaporation possessing a composition of Ti.sub.a Si.sub.b (wherein "a" and "b" stand for atomic percentages respectively falling in the ranges of 75 at %.ltoreq.a.ltoreq.85 at % and 15 at %.ltoreq.b.ltoreq.25 at %, providing a+b=100 at %). Deposition is effected by a sputtering process or ion plating process in an atmosphere of an inert gas containing a nitrogen-containing reaction gas while controlling the feed rate of the reaction gas into a chamber in such a manner that the partial pressure of nitrogen is kept constant or varied continuously or stepwise. By this method, there can be obtained a film having fine TiN crystalline particles uniformly dispersed in the matrix phase of Ti--Si amorphous metal or a film of functionally gradient structure in which the ratio of fine TiN crystalline particles dispersed in the matrix phase increases continuously or stepwise in the direction of thickness of the film.

摘要： A hollow core body for signal transmission cable comprises an inner conductor that employs a compressed bunched conductor formed by bunching and compressing plural strands such that a cross-section of the compressed bunched conductor is substantially circular, and a hollow insulating core that includes an inner annular member, rib members, an outer annular member, and hollow members. Accordingly, as almost no recesses are produced on the circumferential surface of the compressed bunched conductor, weakening of the mechanical strength due to presence of recesses on the circumferential surface of the inner conductor can be suppressed.
