Abstract
A iron-based amorphous alloy thin strip having a chemical composition represented by a chemical formula of FexBySiz (wherein x is 78-83 at %, y is 8-15 at % and z is 6-13 at %), wherein the number of air pockets at a surface contacting with a cooling roll is not more than 8 pockets/mm2 and an average length in a circumferential direction of the roll is not more than 0.5 mm.
Claims8
An iron-based amorphous alloy thin strip having a chemical composition represented by a chemical formula of FexBySiz (wherein x is 78-83 at %, y is 11-15 at % and z is 6-13 at %), wherein a number of recesses on a surface that contacted a cooling roll during formation of the thin strip is not more than 8 pockets/mm2 and an average length of the recesses in a circumferential direction of the roll is not more than 0.5 mm.
