N2 - Aeroengine parts are manufactured mostly from high-strength titanium alloys to meet aeroengine requirements, and shot peening is used to improve the fatigue life of such parts. Shot peening introduces compressive residual stress within the impact layer, and different shot-peening conditions produce different residual-stress fields. In this paper, the residual stress induced by shot peening is investigated. Different shot-peening parameters (air pressure, flow rate, nozzle speed, distance), paths, and sequences are planned for block and thin-plate specimens, and their effects on the consequent residual stress are investigated. The air pressure, flow rate, and nozzle speed have large effects on the residual stress, as do the shot-peening sequence and path, thereby providing technical support for the subsequent work of optimizing the residual stress after shot peening.
