Abstract
Angular dependent magnetic Barkhausen noise energy signal measurements were performed on two similar pipeline steel samples up to tensile st resses of 330 MPa. Variations between the stress dependence of the ene rgy signals at five investigated positions were interpreted in terms o f the relative proportion of three stress-dependent mechanisms for mod ifying the magnetic properties of steel. These were; the change in the number and in the orientation of 180 degrees domain walls and the mod ification of pinning barriers.
