Abstract :
Recent researches on high silicon iron alloys in our laboratory are presented. In the field of 6.5%Si-Fe alloy sheet, the substitution of 1.5% aluminum for silicon improves the cold workability and retains the good magnetic properties of 6.5%Si-Fe sheet. By a splat cooling technique, XSi.YAl.(100-X-Y). Fe ribbons ( 
) in the crystalline state were prepared. They are remarkably flexible and can be easily cold-rolled, and after annealing are mechanically very soft. The good magnetic properties are obtained after annealing at 1200°C for 1hr in vaccum. The magnetic properties of 6.5%Si-Fe ribbon are improved by the double heat treatment. The initial permeability versus frequency curves for 6.5%Si-Fe ribbon are nearly flat up to 100kHz. The ribbon could be used in high frequency magnetic cores.
