ABSTRACT:
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.
