The Influence of Ferrite Inequigranularity on the Magnetic Properties of Silicon Electrical Steel

This article discusses the influence of ferrite inequigranularity on magnetic properties of silicon electrical steel. The influence of inequigranularity on specific magnetic losses has been quantitatively estimated at different grain size and alloying level, and the validity of this property has been confirmed. The influence of inequigranularity becomes more obvious with increase in alloying with silicon and aluminum and decreases to an insignificant level with increase in the average grain size of the ferrite phase.
