Abstract:  
Shot peening is a mechanical surface treatment widely used in industry to improve the fatigue properties of components. It appears that the parameters of this process must be adjusted to new alloys and/or manufacturing techniques to reach even better fatigue properties. The purpose of this study is to determine the optimal shot peening conditions for the beta titanium alloy Ti10V- 2Fe-3Al in order to optimize fatigue life, taking into account different machining conditions. This development was carried out during CONDOR project. Keywords: Shot peening, Fatigue, beta titanium, Ti 10V-2Fe-3Al, fractography, surface roughness
