Classification of Grain-Oriented Electrical Steel Sheets by Magnetic Barkhausen Noise Using Time-Frequency Analysis and Selected Machine Learning Algorithms

Applied Sciences, 2022
In this paper, a combination of Magnetic Barkhausen Noise (MBN) and several classical machine learning (ML) methods were used to evaluate both the grade and the magnetic directions of conventional and high grain oriented electrical sheets subjected to ...

Dynamics of a ferromagnetic domain wall: avalanches, depinning transition and the Barkhausen effect [PDF]

, 1998
We study the dynamics of a ferromagnetic domain wall driven by an external magnetic field through a disordered medium. The avalanche-like motion of the domain walls between pinned configurations produces a noise known as the Barkhausen effect. We discuss

Case depth in SAE 1020 steel using barkhausen noise [PDF]

Materials Research, 2013
The most widely used thermochemical process for surface hardening of steels is case hardening. Using several different heat treatments, martensitic surface layers were formed on SAE 1020 steel into which carbon had been diffused.

Influence of Components Bending on the Consecutive Plasma Nitridation and Barkhausen Noise Emission

Communications, 2019
This paper deals with the non destructive evaluation of components after the plasma nitridation via the Barkhausen noise techniques. Effect of different surface states before the plasma nitriding is studied via the non destructive Barkhausen noise ...

Modeling Barkhausen Noise in Magnetic Glasses with Dipole-Dipole Interactions

, 2015
Long-ranged dipole-dipole interactions in magnetic glasses give rise to magnetic domains having labyrinthine patterns. Barkhausen Noise is then expected to result from the movement of domain boundaries which is supposed to be modeled by the motion of ...

Magnetic Barkhausen Noise in quenched carburized steels

Journal of Physics: Conference Series, 2011
Steels with different carbon content, 0.11%C and 0.48%C were submitted to a heat treatment for carburization in the surface. The samples were analyzed after several types of heat treatment, including quenching for producing martensite. The Magnetic Barkhausen Noise (MBN) is directly related to the microstructure. Samples with lower carbon content, have

Barkhausen noise in soft amorphous magnetic materials under applied stress

, 1998
We report experimental measurements of Barkhausen noise on Fe_{64}Co_{21}B_{15} amorphous alloy under tensile stress. We interpret the scaling behavior of the noise distributions in terms of the depinning transition of the domain walls.

Ferrite-Martensite Steels Characterization Using Magnetic Barkhausen Noise Measurements

ISIJ International, 2004
Magnetic Barkhausen noise measurements have been carried out to characterize Ferrite-Martensite steels. Using thermal treatments, the volume fraction and the carbon content of martensite were varied in reasonable proportions. The results indicate that the Barkhausen noise measurements can easily allows us to distinguish the two phases, ferrite and ...
