Effect of grain size, deformation, aging and anisotropy on hysteresis loss of electrical steels

The investigation of the effect of cold deformation, anisotropy, aging and grain size on the shape of the hysteresis curve of non-oriented electrical steels shows that most of the hysteresis energy is dissipated in the high-induction region (above the maximum permeability induction). It indicates that more attention should be given to the energy dissipation mechanisms in that region, such as the domain annihilation and nucleation
