摘要： An amorphous Co-based metal filament having a circular cross-section made of an alloy composed mainly of Co-Si-B or Co-Me-Si-B (wherein Me is at least one metal selected from the group consisting of Fe, Ni, Cr, Ta, Nb, V, Mo, Mn, W and Zr). This filament is produced by jetting the above alloy into a rotating member containing therein a cooling liquid through a spinning nozzle having a hole diameter which is determined according to the amorphous metal-forming ability (critical thickness to form an amorphous phase) to thereby cool-solidify the jetted molten alloy and form a filament, and then winding the filament continuously on the inner walls of the rotating member by the rotary centrifugal force thereof. This amorphous metal filament is corrosion resistant, is tough and has high electromagnetic characteristics, and is very useful as industrial materials, such as electric and electronic parts, composite materials and fibrous materials.

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.
