This paper presents results of measurements of the effect of uniaxial tensile stresses of up to 85 MPa on Barkhausen activity and magnetic properties of AISI 4130 and AISI 4140 steels. The results showed that the location of maximum Barkhausen activity was very close to the coercive point. Barkhausen peak height and the total number of pulses were affected by the stress, although there was considerable scatter in some of the results so that it was not clear how the peak height of the AISI 4130 varied with stress.
