The characteristics of the Barkhausen noise phenomenon are investigated for various crystalline microstructures of plain steels. The measurements of the magnetic Barkhausen noise (MBN) and of the acoustic Barkhausen noise (ABN) are performed using th

The aim of this work is to measure and characterize the ferromagnetic noise from high purity iron and 130 p.p.m. carbon–iron alloy in various physical and metallurgical conditions. This is the basis of an industrial development of Barkhausen noise

The Barkhausen noise technique is sensitive to the microstructure of the ferromagnetic materials. The parameters amplitude and position of the peak-shaped Barkhausen signal can be applied for non-destructive characterisation of steel (heat treatment,

Barkhausen noise is generated by the rapid and irreversible motion of Bloch walls within ferromagnetic materials, when submitted to mechanical stresses or external magnetic field. Bloch walls motion is influenced by obstacles like dislocations, preci

Barkhausen noise is generated by the irreversible and discontinuous motion of Bloch walls induced by an external magnetic field or a mechanical stress. These wall motions depend on the magnetic structure of the material (magnetocrystalline anisotropy

The Barkhausen effect (or Barkhausen noise)[1], discovered in 1919, was initially identified as the revealing of irreversible and discontinuous changes of magnetisation induced by an external magnetic field[2]. The interest of Barkhausen noise as a n

The multiple fibre cracks phenomenon of a single filament Metal Matrix Composite was investigated all along a tensile test by using acoustic emission measurements. It appears that the same mean fibre critical length, from Kelly’s model /4/, can be
