ORIENTED ELECTRICAL STEEL SHEET HAVING LOW CORE LOSS AND METHOD OF MANUFACTURING SAME

摘要

Low core loss oriented electrical steel sheet having a surface coating that has a Young's modulus that is not less than 100 GPa and a differential of thermal expansion coefficient relative to the sheet base metal that is not less than 2 X 10<-><6>/K and which contains not less than 10 percent, by weight, of crystallites with an average size of not less than 10 nm and an average crystal grain diameter that does not exceed 1000 nm, and a method of manufacturing same.
