“…In the case of heat treated and quenched steels, there has been found a connection between initial permeability and RMS (root mean square) of MBN [6]. The same relation can be used to estimate mechanical hardness.…”

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.

Interpretation of Magnetic Barkhausen Noise Bursts in Low Frequency Measurements

Experimental results allow the identification of three main magnetic Barkhausen noise bursts, each occurring at a different applied field. Magnetostrictive effects can be related to the 1st and 3rd bursts, because closure domain walls are created and/or eliminated. The 2nd burst occurs at the coercive field and it is usually the most intense, and is attributed to domain wall movement. The analysis of the three main bursts gives an important insight on how stress may affect the losses and magnetic Barkhausen noise. A brief review is also presented about the magnetic Barkhausen noise technique.

“…The grain boundaries act as pinning centers for dw pinning [ 30–32 ] and therefore result in larger coercivities. [ 33–37 ] Dislocations and residual stresses in the material due to deformation also lead to an increase in coercivity. [ 38–40 ] Residual stress results in preferred directions of magnetization and therefore in magnetoelastic anisotropy.…”

Ferritic steel has the potential to act as a medium for magnetic storage of certain information, for example, to document the history of parts. The material is expected to play a role in supporting intelligent production processes and logistics routines for industrial internet applications. For writing and reading stable magnetic codes into steel, it is necessary to investigate and understand the corresponding requirements of the material. Both sensitively depend on characteristic microstructural details and related magnetic properties. They are either already present in the material or may be locally achieved in the code area by supplementary hardening methods.
