Abstract:  
Shot peening was performed on aluminium 7010T7651 using cast steel shot at various intensities. Test specimens were then subsequently anodised prior to fatigue testing. There is a similar improvement in fatigue performance from shot peening using both intensities compared with unpeened and anodised test results. As part of the normal corrosion protection aluminium 7010T7651 parts are normally anodised. The anodising process is known to have an adverse effect on fatigue performance. These results indicate that the intensity of shot peening before anodising does not have a strong influence on fatigue performance of anodised aluminium 7010T7651 material.
