Stress-Driven Magnetic Barkhausen Noise Generation in FeCo Magnetostrictive Alloy
IEEE transactions on magnetics, 2022Stress-driven magnetic Barkhausen noise (MBN) can be potentially used to develop a high-sensitivity dynamic force sensor. MBN is a compositional pulse due to the domain wall movement in ferromagnetic material induced by the external field. In this study,

Influence of magnetizing parameters on the magnetic Barkhausen noise
IEEE Transactions on Magnetics, 1992Magnetic Barkhausen noise (MBN) measurements were made on a sample of pipeline steel as functions of magnetizing frequency and AC flux density in the sample. The observed MBN responses suggest a strong dependence on these magnetizing parameters. With increasing flux density in the sample, the MBN activity initially increases but finally begins to ...

Magnetic Barkhausen Noise for Characterization of Recovery and Recrystallization
IEEE Transactions on Magnetics, 2010The capacity of magnetic Barkhausen noise (MBN) measurements to characterize recovery and the onset and evolution of recrystallization processes occurring during the annealing of cold rolled low carbon steel is analyzed. Cold rolled low carbon steel samples were isothermally annealed at laboratory under different conditions in order to promote various ...

Dual-Phase Steels Characterization Using Magnetic Barkhausen Noise Measurements
Materials Science Forum, 2005Magnetic Barkhausen noise measurements have been carried out to characterize ferritemartensite duplex microstructures and industrial Dual-Phase steels. We have first studied ferritemartensite duplex steels, for which the volume fraction and the carbon content of martensite were higher than for industrial Dual-Phase steels.

Magnetic Barkhausen noise analysis of stress in steel
Current Applied Physics, 2004Abstract When a changing magnetic field is applied to a magnetic material, the domain walls move so domains aligned close to the field direction grow at the expense of those that are less aligned. The movement occurs in a series of sudden jumps leading to magnetic Barkhausen noise (MBN).

Magnetic Barkhausen noise: stress-dependent mechanisms in steel
IEEE Transactions on Magnetics, 1996Angular dependent magnetic Barkhausen noise energy signal measurements were performed on two similar pipeline steel samples up to tensile stresses of 330 MPa. Variations between the stress dependence of the energy signals at five investigated positions were interpreted in terms of the relative proportion of three stress-dependent mechanisms for ...
