<p>A method of bundle-drawing comprising a step of reduction in sectional area of a composite wire into a predetermined size is disclosed. The composite wire is comprised of metallic filaments continuous in longitudinal direction and a matrix of metallic material different from that of said metallic filaments and containing the metallic filaments. The composite wire in which sectional area of the metallic filaments in the composite wire is reduced into not more than 1/35 of their original sectional area without intermediate heat treatment. A method for producing metallic fibers applying the above method is also disclosed. Hard metallic fibers of good accuracy in size and less degradation in property can be produced by less processing steps. Metallic fibers remarkably strengthened by work hardening can be produced. <IMAGE></p> |
