“…The Barkhausen noise emission is smaller for domain rotation rather than for domain wall movement [10]. Several authors [11,12] have confirmed that plastic deformation, with the consequent presence of dislocations in the lattice, also significant reduces the Barkhausen noise emission [13].…”

Microstructures were also characterized by SEM (Scanning Electron Microscope) and hardness tests. MBN measurements were performed on the same sample regions at three excitation frequencies. Different parameters of the measured signals (signal peak position and height, and Root mean square) were calculated. A relationship between mechanical hardness and MBN parameters was found for both materials, with the best correlation coefficient being found in low excitation frequency range.

“…That modification affects also the MBN signal changing the domain structure if the material, yet the character of change is different. It is why simultaneous analysis of both the MBN and MAE signal enhances possibilities of evaluation of microstructure modification when plastic deformation of electric steels is an issue [6].…”

“…Studies have also shown that this technique is sensitive to damage precursors in ferromagnetic materials, and quantities such as the energy and peak value in the Barkhausen signal have been shown to correlate well with level of damage in materials [71][72][73][74][75]. Application of these methods to identify irradiation embrittlement has also been demonstrated to a limited extent in laboratory-scale studies [76][77][78], though the correlations identified are not always linear.…”
