Advances in Fe-Si properties and their interpretation

Recent progress in the preparation and magnetic properties understanding of improved FeSi laminations is shortly reviewed. Attention is devoted, in particular, to methods leading to decreased energy losses, either by means of improved structural properties or high Si content (up to 6.5 wt%). It is put in evidence that the physical modelling of losses, besides providing a rationale for the improvement of the material properties, can lead to very general predictions, where the lamination performances under complex regimes, as found in many devices, can be correctly described.
