Abstract

The heat treatment condition and aging behavior of melt spun amorphous $Fe_{78}B_{13}Si_9$(Metglas 26058-2) were studied with investigating its magnetic properties, i.e., Br, $B_l$, Hc. The optimum heat treatment condition was $400^{\circ}C$, 1 hour under the external field of 200e, and aging was due to the surface oxidation and the appearance of local CSRO (chemical short lange order) with time and temperature. In addition. we investigated the effects of the thickness of the amorphous ribbons on the magnetic properties and aging effect of them.
