Abstract Scope |
Microstructural engineering by means of electromagnetic radiation at extremely high heating and cooling rates can result in unique phase transformation pathways, including spatially selective thermal profiles, for example during partial crystallization in amorphous soft magnetic materials. In this work, we explore radio frequency (RF) induction heating of a range of different metallic alloy systems including bulk crystalline alloys as well as amorphous and nanocrystalline alloys. Simulations of electromagnetic heating effects through RF induction processing were carried out, including the impacts on microstructures and phase transformations. Simulation results were also compared with the results of experimental investigations. A comparison of different induction annealing approaches including longitudinal and transverse flux heating coil configurations, will be presented along with the results of structural and magnetic property characterization. The potential for leveraging RF induction annealing methods for enhanced performance of various types of soft magnetic components and devices will also be briefly discussed. |
