In this paper, we present a nondestructive method based on the Barkhausen noise effect for estimating internal stress profiles, with the goal of controlling bearing raceways to determine the homogeneity of the shot peening process. Given the industrial imperative to characterize parts, our method concentrates on stress profiles in the first 60μm under the surface, in steps of 5 or 10μm. Our results show the efficient use of Barkhausen noise to estimate the residual stress profiles of bearing raceways. A mapping of the stress profiles measured by Barkhausen noise was completed for the entire width of an outer ring raceway. This study confirmed that it is possible to use Barkhausen noise to test the uniformity of the shot peening treatment and to inspect the homogeneity of surface and subsurface stresses on the bearing rings. The proposed method is rapid, well suited to industrial imperatives connected to on-line measurement, and easily adapted to the circular geometries of the bearing rings.

The performance of engineering components under conditions of fatigue can be improved by shot peening. The location and magnitude of the highest residual compressive stress, the depth of the compression zone and the stability of the residual stress state during cyclic loading are critical parameters for maximum utilisation of the advantageous influence of shot peening on fatigue performance. For accurate assessment of fatigue lifetime, residual stresses should be considered because they are algebraically summed with applied stresses. Therefore, the development of a non-destructive testing (NDT) method that has the ability to rapidly monitor surface residual stresses has industrial importance when verifying the achievement of the design goals of shot peening. The utilisation potential of the magnetic Barkhausen noise (MBN) technique in shot peening of ferromagnetic steels includes automated sorting of the components and measurement of surface residual stress. This study aims to establish the correlation between MBN emission and the fatigue life of shot-peened AISI 4140 steel.

It is important to account for residual stress relaxation phenomenon in the design of the component. Specimens of 2024-T351 aluminium alloy were used in this study. The specimens were shot peened under three different shot peening intensities. Cyclic tests for two load magnitudes were performed for 1, 2, 10, 1000 and 10000 cycles. Residual stresses, microhardness and the cold work percentage were measured at initial state and after each loading cycle for the three shot peening intensities and for the two loads. The study revealed that most of the drop in the residual stress, microhardness and cold work happened in the first cycle are dependent on the applied load.

The paper deals with the effect of different shot peening (SP) treatment conditions on the ENAW 7075-T651 aluminium alloy. Suitable residual stress profile increases the applicability and life cycle of mechanical parts, treated by shot peening. The objective of the research was to establish the optimal parameters of the shot peening treatment of the aluminium alloy in different precipitation hardened states with regard to residual stress profiles in dynamic loading. Main deformations and main residual stresses were calculated on the basis of electrical resistance. The resulting residual stress profiles reveal that stresses throughout the thin surface layer of all shot peened specimens are of compressive nature. The differences can be observed in the depth of shot peening and the profile of compressive residual stresses. Under all treatment conditions, the obtained maximum value of compressive residual stress ranges between -200 MPa and -300 MPa at a depth between 250 μm and 300 μm. Comparison of different temperature-hardened aluminium alloys shows that changes in the Almen intensity values have greater effect than coverage in the depth and profile of compressive residual stresses. Positive stress ratio of R=0.1 was selected. Wöhler curves were determined in the areas of maximum bending loads between 30 - 65 % of material's tensile strength, measured at thinner cross-sections of individual specimens. The results of material fatigue testing differ from the level of shot peening on the surface layer.
