Process for producing high strength alloy wire

A process for producing a high-strength alloy wire comprising the steps of forming a cast amorphous alloy having a circular or polygonal cross section from an alloy which exhibits glass transition behavior;

• continuously introducing the amorphous alloy into one or more heating zones arranged in series;
• heating the amorphous alloy at a heating rate of at least 10 K/min to a temperature between the glass transition temperature (Tg) of the alloy and the crystallization temperature (Tx) of the alloy while subjecting the alloy to single stage or multistage drawing in each heating zone such that the drawing stress is controlled by adjusting the feed rate and pulling rate of the amorphous alloy to obtain a wire;
• and, after attaining the desired cross-sectional area, continuously cooling the wire thus attained at a cooling rate of at least 100 K/min to a temperature not higher than (Tg-50 K).

• and, after attaining the desired cross-sectional area, cooling the wire thus obtained to a temperature not higher than (Tg-50 K).
