Abstract

Production of a nanocrystalline soft magnetic iron-silicon-boron alloy magnetic core involves crystallization heat treatment of the amorphous alloy at 250-450 degrees C in a transverse magnetic field of rectangular waveform. Production of a magnetic core of nanocrystalline soft magnetic alloy, of composition more than 60 at.% Fe, 10-20 at.% Si, 0.1-2 at.% Cu, 5-20 at.% B and 0.1-10 at.% of one or more of Ti, Nb, Zr, Hf, V, Ta, Cr, Mo, W and Mn, the sum of Si + B being less than 30 at.%, involves crystallization heat treatment of the amorphous alloy at 250-450 degrees C in a transverse magnetic field of rectangular waveform. An Independent claim is also included for a magnetic core produced by the above process and exhibiting, for a 50 Hz alternating excitation magnetic field of 10 mA/cm maximum amplitude at 25 degrees C, an impedance magnetic permeability ( mu z) of greater than 200000, a remnant induction/saturation induction (Br/Bm) ratio of less than 0.2 and DELTA Bstat and DELTA Bdyn values of greater than 0.2 T.
