Estimation of the Effective Magnetic Properties of Two-Phase Steels

We investigate the predictive performance of specific analytical and numerical methods to determine effective magnetic properties two-phase steels at macroscale. utilize various mixture rules reported in literature for former, some which correspond rigorous bounds, e.g., Voigt (arithmetic) Reuss (harmonic) averages. For latter, we employ asymptotic homogenization together with finite element method (FEM) periodic boundary conditions (PBC). The voxel-based discretization representative volume is conducted digital image processing on existing micrographs DP600-grade steel. show that unlike considered isotropic rules, use only phase fraction as statistical microstructural descriptor, method-based first-order allows prediction both content directional dependence permeability by permitting an accurate consideration underlying geometry.
