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 ...

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 ...
Time-frequency and time-scale analysis of Barkhausen noise signals
(PROFESSIONAL ENGINEERING PUBLISHING LTD, 2009)
Carrying out information about the microstructure and stress behaviour of ferromagnetic steels, magnetic Barkhausen noise (MBN) has been used as a basis for effective non-destructive testing methods, opening new areas 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 ...
