Simulation of magnetic hysteresis loops and magnetic Barkhausen noise of α-iron containing nonmagnetic particles

open access: yesAIP Advances, 2015
The magnetic hysteresis loops and Barkhausen noise of a single α-iron with nonmagnetic particles are simulated to investigate into the magnetic hardening due to Cu-rich precipitates in irradiated reactor pressure vessel (RPV) steels.

Effect of Shot Peening Treatment on Residual Stress and Magnetic Barkhausen Noise of AISI 201LN and AISI 304L Stainless Steels

open access: yesMaterials Research, 2022
12, 2021 This work evaluates microstructural changes and residual stresses on surface samples of AISI 201LN and 304L subjected to shot peening. The residual stresses were measured by Xray diffraction and magnetic Barkhausen noise (MBN) in different shot ...

A spring-block model for Barkhausen noise

open access: yes, 2004
A simple mechanical spring-block model is introduced for studying magnetization phenomena and in particularly the Barkhausen noise. The model captures and reproduces the accepted microscopic picture of domain wall movement and pinning.

Influence of Demagnetization and Microstructure Non-Homogeneity on Barkhausen Noise in the High-Strength Low-Alloyed Steel 1100 MC

open access: yesApplied Sciences
This study deals with two different aspects of the high-strength low-alloyed 1100 MC steel. The first is associated with the remarkable heterogeneity (linked with surface decarburization) in the surface state produced during sheet rolling with respect to

Crackling Noise, Power Spectra and Disorder Induced Critical Scaling

open access: yes, 2001
Crackling noise is observed in many disordered non-equilibrium systems in response to slowly changing external conditions. Examples range from Barkhausen noise in magnets to acoustic emission in martensites to earthquakes.

Increasing the Reuse Potential of High‐Strength Steels by Extending the Fatigue Life through Surface Treatments

open access: yessteel research international, EarlyView.
Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.

Evaluation of the Residual Stress State of 42crmo4 Steel Sheets in a Production Line [PDF]

open access: yesMaterials Research, 2016
The residual stress state of a mechanical component is an important factor in its production planning and in estimates of its lifecycle since it can be responsible for geometric distortions and degradation of fatigue properties.
