摘要： A magneto-impedance element comprises an alloy composed of at least one of Fe, Co and Ni. The alloy has a mixed texture of an amorphous phase and a fine crystalline phase having an average crystal grain size of 50 nm or less. The magneto-impedance element shows a change in impedance in response to an external magnetic field by applying an alternating current. The magneto-impedance element is applied to an azimuth sensor, an autocanceler, or a magnetic head.

摘要： A hard thin film having fine crystalline ceramic particles dispersed in a metallic matrix phase is disclosed. The production of the film is effected by first depositing a substantially amorphous film on a substrate and then heat-treating the deposited film. Deposition of the film on the substrate is carried out by using a source of evaporation having a composition represented by the general formula: Al.sub.a M.sub.b, wherein M stands for at least one element selected from the group consisting of Ti, Ta, V, Cr, Zr, Nb, Mo, Hf, W, Mn, Fe, Co, Ni, and Cu and "a" and "b" respectively stand for atomic % in the ranges of 60.ltoreq.a.ltoreq.98.5 and 1.5.ltoreq.b.ltoreq.40, providing a+b=100. Deposition is effected by a physical vapor deposition process in an atmosphere of an inert gas containing a reaction gas while controlling the feed rate of the reaction gas into a chamber in such a manner that the partial pressure of the react/on gas is kept constant or varied continuously or stepwise. By this method, there can be obtained a hard composite film having fine ceramic particles dispersed in a metallic matrix phase or a dense, hard, and composite film having a composition and structure obliquely varied from a substantially crystalline metallic phase to a crystalline ceramic phase in the direction of thickness of the film.

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： A process for producing amorphous alloy materials having high toughness and high strength from various alloy powders, thin ribbons or bulk materials consisting of an amorphous phase by heating them to a temperature at which intermetallic compounds or other compounds are not produced. During this heating, fine crystal grains consisting of a supersaturated solid solution made of a main alloying element and additive elements and having a mean grain diameter of 5 nm to 500 nm are precipitated and uniformly dispersed in a volume percentage of 5 to 50% throughout an amorphous matrix. In the process, when deformation, pressing or other working is simultaneously conducted with the heating, consolidation or combining of the resultant alloy materials can also be effected in the same production procedure. The amorphous alloy used in the production process preferably comprises Al, Mg or Ti as a main element and, as additive elements, rare earth elements and/or other elements.

摘要： A process for producing an amorphous alloy material characterized by imparting ductility to an amorphous alloy having a supercooled liquid region by giving a prescribed amount of strain at a prescribed strain rate to the alloy in the glass transition temperature region of the alloy. The amorphous alloy may be in the form of spherical or irregular-shaped powders or thin ribbons or in the form of primary consolidated shapes thereof or an amorphous alloy casting. The amount of strain and strain rate are preferably 50% or greater and 2.times.10.sup.-2 /sec or higher, respectively, and the worked amorphous alloy material is preferably allowed to cool in a furnace or spontaneously. Suitable examples of the amorphous alloy to be employed include Al-TM-Ln, Mg-TM-Ln, Zr-TM-Al and Hf-TM-Al alloys, wherein TM is a transition metal element and Ln is a rare earth metal element. The thus obtained amorphous alloy is greatly improved in the prevention of embrittlement in hot working peculiar to the alloy.
