Title:
METHOD FOR MANUFACTURING NANOCRYSTAL ALLOY RIBBON, AND METHOD FOR MANUFACTURING MAGNETIC SHEET
Document Type and Number:
WIPO Patent Application WO/2023/190963
Kind Code:
A1
Abstract:
A nanocrystal alloy ribbon is provided. According to this method for manufacturing a nanocrystal alloy ribbon, when an amorphous alloy ribbon is contacted with a heating body and heated, the heating body is heated to a heating temperature Ta of Tx1+80℃ or more and Tx1+230℃ or less, wherein Tx1℃ is the bcc Fe crystallization onset temperature of the amorphous alloy ribbon measured at a temperature-increase rate of 20 K/min.
