Abstract

In this study the magnetic aging effect on anomalous and hysteresis loss was investigated, as well as its effect on domain morphology. For this purpose, non-oriented fully processed electrical steel with 2.3 wt.% Si - 79 ppm C and non-oriented semi-processed electrical steel annealed at 750 degrees C for 5 hours with 0.4 wt.% Si - 340 ppm C were aged at 150 degrees C. The anomalous loss has been shown to be less affected by the magnetic aging. The increasing of the excitation frequency has induced a reduction on anomalous loss measured on aged steel. All increases presented by total loss were provided by hysteresis loss. The main disturbance in magnetic domain morphology appears to have been caused by different grain orientation. (AU)
