Abstract

PURPOSE:To eliminate the dispersion of magnetism and to obtain excellent magnetic characteristics by regulating the dew point and O2 amt. in the annealing atm. to the prescribed value or below at the time of annealing the Fe-B-Si amorphous alloy thin strip in which B and Si are specified. CONSTITUTION:The Fe-B-Si amorphous alloy contg., by atom, 7-16% B, 4-14% Si and the balance Fe is refined. The thin strip of said alloy is annealed in such a manner that <=30 deg.C dew point and <=0.01vol.% O2 amt. are regulated in the annealing atm. By this method, the thin strip showing the excellent magnetic characteristics of the materials own can be obtd. without the dispersion of the magnetism.
