A finite element microstructure model based on magnetic domain theory has been developed to evaluate magnetic anisotropy in polycrystalline steels, considering crystallographic texture and grain size. The model accurately captures the effects of crystallographic texture, grain size, and vector induction on effective permeability behaviors. Predicted magnetic properties allow for quantitative characterization of magnetic anisotropy, while effective permeability maps visually indicate crystallographic texture from magnetic values. These features have been experimentally validated against commercial grain oriented electrical steel with strong texture and magnetic anisotropy.
A finite element microstructure model with permeability tensors that considers crystallographic texture and grain size based on magnetic domain theory has been developed for the evaluation of magnetic anisotropy in polycrystalline steels. The model has proved capable of capturing the crystallographic texture, the grain size and the vector induction effects on the effective permeability behaviours for typical textures in steels. The predicted magnetic properties as a function of the magnetic field direction enables a quantitative characterisation of the magnetic anisotropy. The predicted effective permeability maps can serve as a visual indication of the crystallographic texture from magnetic values. These features have been experimentally validated against a commercial grain oriented electrical steel featuring strong texture and magnetic anisotropy.
