| Abstract Scope |
Magnetic field-assisted processing is a developing, energy-efficient alternative to current heat treatment processes in the steel industry, which leverages a high static magnetic field to improve processing outcomes. Attempts to precisely tailor steel microstructure using magnetic field-assisted processing are hindered by poor understanding of how the field alters microstructural evolution, particularly when applying an additional field for induction heating and when quenching in- vs. out-of-field. The ongoing investigation of low-alloy carbon steels uses electron backscatter diffraction to examine martensite morphologies and reconstruct prior austenite microstructures, revealing the effects of processing under varied magnetic field strengths and annealing times. The magnetic field increases apparent initial austenite grain growth rates as well as affecting annealing twin morphology. The role of the magnetic field on the martensite variant selection is also investigated. |
