Abstract
Results are reported about the power loss dependence on microstructural parameters in SiFe non-oriented laminations. In particular, the direct influence of grain size and crystallographic texture on hysteresis losses is investigated. A general phenomenological law is provided, by which we are able to enucleate the individual effects of impurity content, average grain size and texture on losses.
