Abstract: AA2014 Al alloy specimens (in the form of plates) have been shot peened to varying intensity levels (0.14 to 0.48 mm ALMEN ā€˜Nā€™) and the effect of shot peening intensity on the subsurface plastic deformation, surface and subsurface residual stress field, depth of peening and microstructure evolution has been investigated. The influence of shot peening intensity on the high stress abrasive wear behaviour has also been investigated. The wear rate reduced significantly due to mild shot peening. Intensive shot peening did not lead to any significant improvement in wear resistance, rather beyond a critical peening intensity, the wear resistance of material starts deteriorating.
