Effect of grain size, deformation, aging and anisotropy on hysteresis lossof 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-i nduction region (above the maximum permeability induction). It indicates th at more attention should be given to the energy dissipation mechanisms in t hat region, such as the domain annihilation and nucleation.
