Metallurgical influences on the magnetic properties of rapidly quenched Fe base alloys
Tóm tắt
Rapid solidification technology is a significant new approach to the production of metallic materials. The application of that technology to magnetic materials has resulted in properties far better than those of comparable materials produced by more traditional processing methods. Much of the developmental work has been guided by metallurgical insights. For Fe base metallic glasses, the considerations include glass formation, mechanisms and kinetics of devitrification, and magnetic stability. Crystallographic ordering, which prevents conventional processing of desirable high solute content Fe—Si and Fe—Si—Al alloys, can be circumvented by rapid solidification.
