The rectified MBN profiles were found to be reversible with respect to loading and unloading, i.e., a profile that was changed by application of stress was recovered when the stress was removed. Characteristics of the profiles (peak height V p, peak position I p and half-width W p) were recorded as a function of applied stressσ. Plots of V p versus σ were S-shaped, with V p reaching a maximum on the tensile side of the graph and a minimum on the compression side. In a more restricted stress range, between −500 and 1,000MPa, V p was an approximately a linear function of σ. The OT specimens showed greater sensitivity to stress than the ST specimens. Another difference was that the OT specimens produced an MBN profile with two overlapping peaks when under compression. The other profile characteristics showed a relationship with stress that ran counter to that of V p, i.e., where V p increased with increasing stress, I p and W p decreased. The observations are discussed in the light of established models of Barkhausen noise.
