| Abstract Scope |
Magnetic field‑assisted processing is an emerging, energy‑efficient alternative to conventional heat treatments in the steel industry, leveraging a high static magnetic field to improve processing outcomes. Attempts to precisely tailor steel microstructure using this approach are hindered by a poor understanding of how the field alters microstructural evolution, particularly when an additional field is applied for induction heating and when quenching in‑versus out‑of‑field. The ongoing investigation of low‑alloy carbon steels uses electron backscatter diffraction to examine martensite morphologies and reconstruct prior austenite microstructures present under varied magnetic field strengths and annealing times. Higher magnetic fields increase apparent initial austenite growth rates and affect annealing twin morphology. Twin connectivity is explored using “Twin Tree,” a graph‑based analysis tool for MATLAB that the authors developed to better capture twin networks in FCC metals from 2D EBSD data. The role of the magnetic field in martensite variant selection is also investigated. |
