In the present work a new system for nondestructive evaluation of applied stress on the pipeline steels surface is proposed. This system is based on applying a magnetic field on the pipe surface, whose direction changes due to rotatory permanent magn

In the present work a model for the correlation between magnetocrystalline anisotropy energy and Barkhausen noise is proposed. The link between the magnetocrystalline anisotropy energy and the magnetic Barkhausen noise is due to the influence of the

This work analyzes the differences between the magnetic Barkhausen noise corresponding to the initial magnetization curve and Barkhausen noise corresponding to one branch of the hysteresis loop in API-5L steel. The outcomes show that the Barkhausen n

Giant magnetoresistance (GMR) sensors have been used in non-destructive testing based on eddy current (NDT-EC). The low-pass filtered GMR-based NDT-EC have been successfully used to estimate the dimensions of artificial near-side cracks in aluminum p

The present work analyzes the influence of electric conductivity on the Magnetic Barkhausen Noise (MBN) signal using a microscopic model which includes the influence of eddy currents. This model is also implemented to explain the dependence of MBN on

This work studies the influence of the maximum applied magnetic field on the angular dependence of the energy of the Magnetic Barkhausen Noise signal in three different API5L pipeline steels. The results show that the shape of the angular dependence

Recent works in the literature have demonstrated that the angular dependence of magnetocrystalline anisotropy energy could be estimated from magnetic Barkhausen noise in carbon steels using the energy of a Barkhausen signal band associated with the m
