RODRIGUEZ, J.L. et al. Dependence of Barkhausen jump shape on microstructure in carbon steel. Rev. mex. fis. [online]. 2008, vol.54, suppl.2, pp.127-129. ISSN 0035-001X.

The present work presents measurements of the Magnetic Barkhausen Noise (MBN) in commercial AISI/SAE 1005 steel samples for different grain sizes. The correlation between the shape of the MBN jump and the grain size is established. The results show the existence of types of MBN jumps. Also, the outcome shows that one of these types of MBN jumps become "squarer" with the decrease of grain size.

Palabras llave : Magnetic barkhausen noise; microstructural defects; grain size; plain steels.
