مستخلص: The residual stress state in subsurface zones is well known to have a significant impact on a component’s properties in terms of fatigue behavior and resistance to wear and corrosion. For this reason, adjusting residual stresses during manufacturing is a major challenge in modern production engineering. In this context, hydrostatic deep rolling of the workpiece surface using adapted parameters enables the targeted introduction of compressive residual stresses into the subsurface layers. Due to specific properties regarding subsurface and topography for functional components in tribological applications, a further machining operation by microfinishing following deep rolling seems to be purposeful. In this research, the applicability of cos α-method as an alternative for sin 2 ψ-measurements and a micromagnetic approach for residual stress assessment was investigated, analyzing deep rolled and microfinished AISI 4140 specimen conditions. After microfinishing of the deep rolled surfaces, favorable compressive residual stresses remain in the subsurface zones, reaching approximately -600 MPa. For all surface states investigated, a good agreement between the two approaches in X-ray diffraction was found. Magnetic Barkhausen noise (MBN) measurements show a good correlation with X-ray data and prove to be well applicable for an efficient assessment of surface integrity in deep rolled and microfinished specimens
