Title:
NON-ORIENTED ELECTROMAGNETIC STEEL SHEET AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2022/196807
Kind Code:
A1
Abstract:
This non-oriented electromagnetic steel sheet has a prescribed chemical composition, and under observation by means of EBSD in a plane parallel to the surface of the steel sheet, when the entire surface area is Stot, the surface area of {100} orientation particles is S100, the surface area of oriented particles for which the Taylor factor M is greater than 2.8 is Styl, the total surface area of oriented particles for which the Taylor factor M is 2.8 or less is Stra, the average KAM value of the {100} orientation particles is K100, and the average KAM value of the oriented particles for which the Taylor factor M is greater than 2.8 is Ktyl, the inequalities 0.20≤Styl/Stot≤0.85, 0.05≤S100/Stot≤0.80, S100/Stra≥0.5, and K100/Ktyl≤0.990 are satisfied.
