**4. Conclusions**

Residual stresses in the AA2024-T3clad and AA2024-T3 specimens for different peening strategies were investigated in this study. The effects of the clad layer, Al foil, choice of advancing direction, overlap as well as peening with two sequences on residual stress profiles were studied. The residual stresses were measured using the incremental hole-drilling technique, and for two shot patterns EBSD measurements were performed in order to study the local orientation changes exemplarily. Furthermore, the influence of one single shot with different energy impacts on the affected surface area was investigated. The conclusions of the study can be summarized as follows:
