Document Type and Number:
Japanese Patent JP7111096
Kind Code:
B2
Abstract:
One embodiment of the present invention provides an Fe-based amorphous alloy ribbon for an Fe-based nanocrystalline alloy, the Fe-based amorphous alloy ribbon being a cooled body of a molten metal that has been applied to a surface of a chill roll, wherein the Fe-based amorphous alloy ribbon includes a recess having a depth of 1 µm or more in a 0.647 mm × 0.647 mm region located in a central part, in the ribbon width direction, of a ribbon surface, which is a cooled surface, in which a maximum area of the recess having a depth of 1 µm or more is 3000 µm2or less; and a method of manufacturing the same.
