Study on the Magnetic Properties and Microstructures in Cold-rolled High Silicon Fe-Si Alloys

摘要

In the Fe-Si system, an alloy with 6.5wt%Si is well known to have phase transition of order-disorder. Until now, several studies have shown that in the rapidly-quenching Fe-6.5wt%Si alloy, the B2 and DO_3 order phases have strong influence on magnetic properties[l-3]. However, it still remains unclear on how the order phases affect the magnetic properties. Therefore, the purpose of this work is to clarify the relationship between magnetic properties and microstructures.
