Current state of the art soft magnetic materials for medium frequency and high power applications are metal amorphous nanocomposite (MANC) alloy systems manufactured through partial devitrification of an initially amorphous precursor. Recent work has demonstrated the potential to dramatically increase the number of crystalline nuclei that form through rapid thermal annealing processes, thereby producing refined microstructures with enhanced soft magnetic performance. In this work, we explore laser-based processing of a range of different alloy systems in order to produce rapid thermal heating profiles in a scalable and manufacturable configuration which can be readily translated to in-line and pilot-scale production facilities. A comparison of traditional and laser annealing approaches will be presented along with the results of structural and magnetic property characterization.
