Magnetic Barkhausen emission in lightly deformed AISI 1070 steel

► Evaluated residual stresses by the magnetic Barkhausen technique. ► Indication about the relevance of micro-and macro-stress components. ► Magnetic Barkhausen measurements were carried out in AISI 1070 steel sheet samples. ► Two different sheets, deformed and non-deformed, are evaluated together. ► Magnetic Barkhausen signal increases when deformed region is below the surface.
