FE-NI BASED SOFT MAGNETIC ALLOYS HAVING NANOCRYSTALLINE STRUCTURE AND MANUFACTURING METHOD OF MAGNETIC ALLOYS

摘要

Disclosed is a Fe—Ni based soft magnetic alloy having microcrystalline particles that are essentially uniformly distributed through an amorphous substrate.;The soft magnetic alloy of the present invention may be represented generally as (Fe _1-x Nix) aMb (B _1-y Siy) c.;Wherein M is a metal selected from the group consisting of Mo, Cr, Hf, Nb, Ta, Ti, V, W, Zr.;The amount "X" is 0.2 to 0.9; a is 60-90; b is 0.1 to 10; y is 0 to 0.5, C is 0.1 to 30, and the amount of the remaining impurities added is 100.;The present invention also provides a process for preparing a microcrystalline alloy and optimizing the specific magnetism of the alloy through two stage annealing.
