ResumoThe influence of applied tensile stress and grain size on Magnetic Barkhausen Noise and hysteresis loops in 1005 commercial steel is studied in this work. The peak amplitude of the Barkhausen voltage increases with the applied stress, reaching a maximum value and then beginning to decrease at higher tensile stress. This behavior is explained regarding the domain wall dynamics by the combined effect of the magnetic field and applied stress on the domain wall motion. The present study also reveals that the stress dependence on the MBN voltage and on the magnetic hysteresis loop is influenced by the grain size of the samples. The results show that MBN can be utilized to evaluate changes in the microstructural and mechanical properties of commercial carbon steels.
