Abstract

By using a rapid quenching method, Fe-Go-Si alloy ribbons were prepared and their grain structure and magnetic properties were observed. The size of ribbons obtained are 50∼70 μm in thickness and 2 ∼4 mm in width and their average grain size is 2∼ 20 μm. By annealing ribbons in a vacuum atmosphere the grain grew to be about 1∼2 mm and the ribbons had
