Induction-coupled thermomagnetic processing has been shown to reduce energy costs of heat-treating steels by up to 95% and result in mechanical property improvements. These benefits result from changes to the free energy and kinetics of the steel phase changes. The applied field also results in changes to the shape of the precipitates. However, lattice strains around precipitates also impact nucleation and precipitate shape. In this work, we use a phase field model to compare the impact of lattice strain and the applied magnetic field on the nucleation and shape of precipitates during steel heat treatment. We compare the impact of applied field and lattice strain on the growth of nuclei in single crystal steel and on the nucleation and growth in polycrystal steel.
