Title:
AMORPHOUS METAL RIBBON, METHOD FOR PROCESSING SAME, AND METHOD FOR PRODUCING LAMINATE
Document Type and Number:
WIPO Patent Application WO/2019/208651
Kind Code:
A1
Abstract:
Provided is a method capable of suppressing the generation of cracks or fractures in an amorphous metal ribbon during machining of the amorphous metal ribbon. Also provided is a method for processing an amorphous metal ribbon, wherein the amorphous metal ribbon is machined after being vibrated or while being vibrated. Specifically, in the method for processing an amorphous metal ribbon, the amorphous metal ribbon has a saturation magnetostriction of at least 1 ppm, and the vibration is caused by magnetostriction of the amorphous metal ribbon. Alternatively, in the amorphous metal ribbon, a portion locally vibrated by a machining tool is machined.
