Abstract: A heating process of improving the magnetic and mechanical properties of ferromagnetic amorphous alloys wherein the amorphous ribbon is treated with rapid heating and rapid magnetic domain impacting in a direct heating manner by means of pulsed high current to improve the magnetism of ferromagnetic amorphous alloys with reduced or eliminated the annealing embrittlement thereof.The heating process is performed in the following conditions:pulse current density: J.gtoreq.10.sup.3 A/cm.sup.2pulse duration: tp=1 ns-100 msfrequency: f=1 Hz-1,000 Hzheating time: tn=1 sec.-100 secs.
