Abstract:  
In this work as main aim, the process parameters of inner shot peening by air-blast process combined with special nozzles are analyzed. To guarantee a flow direction, diverting features are used to peen the inner surface of tubular small complex geometry elements with uniform results. The analytical relationships between them are developed and coupled to existing analytical compressive residual stress and Almen Intensity prediction models in order that, by numerical calculation, the resulting process profiles could be used in early stages of product/process development or for the improvement of currently running set-ups.
