NANOCRYSTALLINE ALLOY STRIP AND MAGNETIC CORE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a nanocrystalline alloy strip for improving corrosion resistance and toughness and capable of obtaining excellent magnetic characteristics, and also to provide a magnetic core using the same.SOLUTION: Disclosed is a nanocrystalline alloy strip containing Fe, P and Cu which is characterized in that the crystal grain size of nanocrystal precipitated on the surface 1 is smaller than that of the nanocrystal precipitated in a parent phase 2.
