| Abstract Scope |
Electrical steels are one type of soft magnetic materials. They are based on Fe-Si alloys, and they are widely used for magnetic cores in transformers and electric motors. It is well known that Fe-6.5Si wt% is the most efficient composition that has been developed so far. However, at such high silicon concentration (6.5wt.% = 12.1 at.% Si in Fe) the workability of the alloy is so bad that it makes it extremely difficult for industrial rolling production.
Our project approaches this problem via two different solutions. First, we developed a machining-based technology that suppresses the mechanisms that lead to cracking during traditional rolling. Second, we develop a high-resistivity electrical steel alloy with up to 35% reduction of core losses (compared to commercial alloys with ~ Fe-3.2Si wt%) but maintaining good workability. |
