Impact of the STFT Window Size on Classification of Grain-Oriented Electrical Steels from Barkhausen Noise Time–Frequency Spectrograms via Deep CNNs

open access: yesApplied Sciences
The Magnetic Barkhausen Noise (MBN) is a non-destructive testing method, which, due to its high sensitivity to changes in the microstructure of the material, is increasingly being applied with success as a tool for evaluation of magnetic material state ...

Magnetic Barkhausen Noise in Quenched Carburized Nickel-Steels

open access: yes, 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 Barkhausen noise (MBN).

Barkhausen noise emission in hard milled surfaces of steel C55

open access: yes
This paper deals with the application of the Barkhausen noise technique in the nondestructive monitoring of hard milled surfaces. The paper discusses strong magnetic anisotropy linked with microstructural transformations of a machined surface with regard

Preliminary study: Barkhausen noise evaluation on the Hardening Depth of Induction-hardened carbon steel

open access: yes, 2017
Induction hardening depth evaluation by means of Barkhausen noise (BN) technique is one known non-destructive evaluation (NDE). The acquired signal, nevertheless, is not easy to be interpreted owing to information and materials complexity.
