Abstract (en)
[origin: EP3050977A1] A method for producing an Fe-based nano-crystal alloy ribbon, includes a heat treatment step of heating a nano-crystallizable Fe-based amorphous alloy ribbon to a crystallization temperature region and cooling the nano-crystallizable Fe-based amorphous alloy ribbon. In the heat treatment step, a magnetic field is applied in a width direction of the alloy ribbon in a temperature range during a temperature-increasing period, the temperature range including at least a part of a temperature range from a temperature lower by 50°C than a crystallization start temperature to a temperature higher by 20°C than the crystallization start temperature and not exceeding a temperature higher by 50°C than the crystallization start temperature, the crystallization start temperature being defined by a differential scanning calorimeter.
