The impact of stress on changes in magnetization is one of the most complex issues of magnetism. Magnetic techniques are the most important non-destructive testing technologies to characterize the mechanical features of ferromagnetic materials based on the physical principle of magnetic-stress coupling. Magnetic Barkhausen Noise measurement was used in order to estimate stress state in boat welding. The results have shown that magnetic properties of ferromagnetic materials are stress-dependent. A qualitative correlation was found between places with residual stress and areas with increased values of the gradients of the magnetic Barkhausen noise components. Further research is now in progress in order to develop the quantitative relationships.

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 180odomain 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
