Abstract Scope |
Controllable and fast heating profiles provide unique capabilities to realize enhanced soft magnetic properties of amorphous and nanocrystalline materials in conventional nanocrystalline alloys, as well as alloy chemistries for which carefully controlled annealing processes play a critical role in realizing desired properties tailored within a large degree of flexibility. In this work, we explore radio frequency induction heating processing of a range of different alloy systems in order to produce rapid thermal heating profiles enabling nanocrystallization. Simulation of electromagnetic heating effects and impacts on microstructures and phase transformation upon heat generation were performed. A comparison of traditional and induction annealing approaches will be presented along with the results of structural and magnetic property characterization. |
