Abstract:
An amorphous Fe-B-Si alloy and article made therefrom is provided having improved castability while maintaining good magnetic properties, ductility and improved thermal stability. Fe-B-Si alloys containing 0. 1-4. 0% Cr, in atomic percent, have improved castability and amorphousness. An alloy is provided generally consisting essentially of 6-10% B, 14-17% Si, 0. 1-4. 0% Cr, and the balance iron, and no more than incidental impurities. A method of casting an amorphous strip material from the alloy is also provided.
