A study of plastic deformation around a defect using the magnetic Barkhausen noise in ASTM 36 steel
(ELSEVIER SCI LTD, 2008)
The present work presents the measurements of the magnetic Barkhausen noise (MBN) in ASTM 36 steel samples around a pit under plastic deformation. The contour maps obtained from these Barkhausen noise measurements are ...
Nondestructive inspection of plastic deformation in commercial carbon steels using magnetic Barkhausen noise
(SOC MEXICANA FISICA, 2008)
The present work shows measurements of the Magnetic Barkhausen Noise (MBN) in commercial AISI/SAE 1045 and ASTM 36 steel deformed samples. The correlation between the MBN root mean square, Barkhausen signal profile and MBN ...
A Comparison Of The Use Of Critically Refracted Longitudinal Waves And Magnetic Barkhausen Noise For Stress Measurement In Api 5l X70 Steel

Microstructural and Residuals Stress Analysis of Friction Stir Welding of X80 Pipeline Steel Plates Using Magnetic Barkhausen Noise
(2019-12-01)
Friction stir welding is a solid-state joining method conducted under large stress and strain conditions at low peak temperatures when compared to arc welding. Friction stir welding produces a large variety of microstructures ...
Magnetic Barkhausen Noise in Quenched Carburized Nickel-Steels
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
Two steel sheets, one with 5% Ni and another with 10% Ni, were submitted to carburization and quenching, obtaining a microstructure with martensite and retained austenite. These steels were characterized with magnetic ...
Simulation of the Barkhausen Noise using random field Ising model with long-range interaction
(ELSEVIER SCIENCE BV, 2009)
We present a method to simulate the Magnetic Barkhausen Noise using the Random Field Ising Model with magnetic long-range interaction. The method allows calculating the magnetic flux density behavior in particular sections ...
Fast detection of the magnetic easy axis on steel sheet using the continuous rotational Barkhausen method
(ELSEVIER SCI LTDOXFORD, 2012)
The magnetic behaviour of most commercial ferromagnetic steels is usually anisotropic presenting a magnetic easy axis. Changes in the direction of this axis can be related to mechanical changes and anomalies that occur in ...
Relation between magnetic Barkhausen noise and hardness for jominy quench tests in SAE 4140 and 6150 steels
(New York, 2013-01-30)
he nondestructive Magnetic Barkhausen Noise (MBN) technique was applied for the evaluation of SAE 4140 and SAE 6150 steels after a Jominy end-quench test. Microstructures were also characterized by SEM (Scanning Electron ...
Statistical properties of Barkhausen noise in amorphous ferromagnetic films

Modeling of Effect of Plastic Deformation on Barkhausen Noise and Magnetoacoustic Emission in Iron With 2% Silicon
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
Before one models the effect of plastic deformation on magnetoacoustic emission (MAE), one must first treat non-180 degrees domain wall motion. In this paper, we take the Alessandro-Beatrice-Bertotti-Montorsi (ABBM) model ...
