Abstract Scope |
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 both conventional and novel rapid thermal annealing techniques including flash annealing as well as RF electromagnetic radiation assisted processing. A comparison of traditional and various rapid thermal annealing approaches will be presented along with the results of structural and magnetic property characterization. The future outlook for the application of novel thermal processing strategies will also be discussed in detail. |
