    摘要: The present invention provides high corrosion-resistant aluminum-based alloys having a composition represented by the general formula Al.sub.x M.sub.y (wherein: M is one metal element selected from the group consisting of Y, La, Ce, Nd and Sm; and x and y range from 75 to 98 atomic percent and from 2 to 25 atomic percent, respectively), the aluminum-based alloy containing at least 50% by volume of amorphous phase. The aluminum-based alloys are especially useful as high corrosion-resistant, high strength, high heat-resistant materials in various applications and, since they exhibit superplasticity in the vicinity of their crystallization temperature, they can be processed into various bulk materials, for example, by extrusion, press working or hot-forging at the temperatures within the range of the crystallization temperature .+-.100.degree. C.

    摘要: A perpendicular magnetic recording medium is formed of a substrate having 5.times.10.sup.5 -5.times.10.sup.9 fine projections per mm.sup.2 on the surface thereof, said projections having heights in the range of 0.01-10 .mu.m and diameters in the range of 0.01-1 .mu.m, and a ferromagnetic material deposited uniformly in a columnar form on the projections. The recording medium is produced by providing in advance fine projections, the heights and diameters of which are 0.01-10 .mu.m and 0.01-1 .mu.m respectively, on the surface of a substrate to a density of 5.times.10.sup.5 -5.times.10.sup.9 projections per mm.sup.2, and then causing a ferromagnetic material to deposit on the substrate from a vapor phase in such a way that the deposited material is preferentially allowed to adhere onto the projections and then to grow the ferromagnetic material in a direction perpendicular to the plane of the substrate. The present invention has expanded the ranges of usable substrate-forming materials and recording materials, i.e., ferromagnetic materials, and has also simplified the production process.

    摘要: A level gauge for liquid helium comprising a sensing element in the form of a ribbon wire made of superconductive alloys and a tube supporting the sensing element, which tube is inserted into liquid helium upon measurement. The superconductive alloys are represented by a formula Zr.sub.100-x.(Ru.sub.y.Rh.sub.1-y).sub.x in which x represents contents of Ru and/or Rh in atomic % and in a numerical value of 22.5.ltoreq.x.ltoreq.27.5 and y represents a numerical value of 0.ltoreq.y.ltoreq.1. The alloys are made of an amorphous phase obtained by rapid quenching a molten alloy material and have a superconducting transition temperature, Tc, of 4.2.degree. to 4.5.degree. K. When the level gauge is immersed in liquid helium, a portion of the sensing element below the level of the liquid helium has a zero electric resistance because of the superconductivity of the alloy, so that the level of the liquid helium can be detected by a variation in resistance of the sensing element.

    摘要: Amorphous metal filaments having a substantially circular cross-section comprising an alloy containing Fe as a main component, and a process for producing such amorphous metal filaments, are described; the process comprises jetting a molten alloy having amorphism forming ability into a revolving body containing a cooling liquid from a spinning nozzle to form a solidified filament by cooling, and continuously winding the filament on the inner wall of said revolving body by means of the centrifugal force of said revolving body, wherein the circumferential rate of revolution of said revolving body is equal to or higher than the rate of jetting of molten metal from the spinning nozzle. These metal filaments have good corrosion resistance, toughness, and high magnetic permeability and are very useful in various industrial applications, such as electric and electronic parts, materials for reinforcement, and fiber materials.

An amorphous iron-based alloy which contains not more than 30 atom % of at least one element selected from the group consisting of Co, Ni, Ta, Nb, Mo, W, V, Mn, Ti, Al, Cu and Zr in addition to the components making up the aforementioned alloy excels in amorphous texture of forming ability and fatigue property.
