Abstract:  
Shotpeening is a simple and often used process of surface treatment. It influences the subsurface layers and can lead to hardening, formation of residual compressive stress, changes in roughness and to phase transformations. To improve the fatigue strength, shotpeening is frequently applied to motor vehicle parts, aerospace components, strings, screws and gears. Fatigue life curves are shown for shot peened C35V steel and 30CrNiMo8V steel.
