Abstract:  
Shot peening to extend fatigue life and prevent stress corrosion of gas turbine components is not a new practice. Yet, it is often bypassed by engineers whose thinking is oriented to solving premature failure problems through material and design changes. For a great many moving as well as stationary components, shot peening is an easier and less expensive option. But to appreciate its value in helping to increase longevity of compressor discs, tie rods, compressor blades, gears, shafts and the like, one must understand the origin of most fatigue and stress corrosion failure.
