ABSTRACT:
A method and apparatus of dynamic heat treating the ferromagnetic amorphous alloys by applying AC current or pulsed high current on the alloys in the form of a ribbon are disclosed. The amorphous ribbon is continuously passed through a pair of electrodes from which AC current is conducted on the amorphous ribbon to perform a Joule heating. A DC magnetic field is applied on the amorphous ribbon preferably along a length direction thereof to improve the soft magnetic properties of the amorphous alloys. The DC magnetic field can be applied on either the section of the amorphous ribbon between the pair of electrodes or the section that has already been heat treated. With the method and apparatus, ferromagnetic amorphous alloys with improved magnetic properties such as greater magnetic induction, lower coercivity and low hysteresis loss are resulted and the annealing embrittlement is avoided.
