Applied magnetic fields are expected to provide novel routes for microstructural manipulation – including texturing and phase formation, distribution, and evolution – and to reduce processing times or temperatures. However, as the field strengths necessary to effect significant and desired microstructural changes may be quite large, it is valuable to evaluate microstructural evolution through modeling. Several meso-scale modeling approaches are being employed to determine the response of metallic microstructures to magnetic fields including Monte Carlo (texture evolution in systems with asymmetric susceptibility), and thermodynamic/CALPHAD (shifts in equilibrium phases and phase boundaries). In particular, several descriptions of the magnetization of phases as a function of alloying are evaluated with respect to their fidelity near transformation temperatures.
