Improvement of magnetic and mechanical properties of amorphous alloys by pulse high current

摘要

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 magnetization in a direct heating manner by means of pulsed dc or ac high current to improve the magnetism of ferromagnetic amorphous alloys with much reduced or eliminated annealing embrittlement thereof.;The heating process is performed in the following conditions:
