heal.abstract	Results of an experimental study of electrical steel annealed at 500, 600, 700 °C and subsequently cooled via quenching or air, are presented. The samples have been characterized with respect to their magnetic properties using Magnetic Barkhausen Noise (MBN) and major and minor loop (B-H) measurements. MBN increases slightly with the annealing temperature especially in the quenched samples. The B-H loops suggest that the prevalent magnetization reversal mechanism in the air cooled samples is domain wall propagation, while in the quenched samples non 180o domain rotation seems to be significant approaching the high induction region. Scanning Electron Microscopy studies show a more homogeneous texture after annealing which in the case of the quenched samples is accompanied by not fully formed grain boundaries and orientation along he easy axis © (2012) Trans Tech Publications.	en
