dc.description.abstractAA7075 alloy is exposed to severe shot peening (SSP) with an Almen intensity of 20A. The microstructure is analyzed via FEGSEM and EBSD microscopy. X-ray diffraction (XRD) analysis is used to evaluate the crystallite size in terms of FWHM measurements. The residual stress measurements show a thicker compressed layer (600 mu m) formed by SSP. Microhardness improvements are observed as 30% on topmost surface and releases substantially after 600 mu m. Coefficient of friction (COF) of treated material remains higher throughout the sliding distance, however, is reduced particularly in the early stage of sliding distance for the wear load of 20 N. The effect of SSP is vanished particularly at lower loads with longer sliding distances. Besides, improvement on fatigue behavior is observed after SSP despite the increase of roughness remarkably.en_US
