Abstract:

Shot peening procedures developed over the past 40 years have resulted in substantial improvements in fatigue properties and stress corrosion resistance of high-strength alloys. These improvements have been observed in shot-peened specimens and components of high-strength steels, aluminum alloys, titanium alloys, and other engineering alloys. This report contains information on peening procedures that have been used in processing specimens and components to achieve these improvements in performance. Certain precautions are pointed out that should be observed in order to obtain the improved properties that have been attributed to the peening process. Some of the peening programs cited in this report indicate the peening intensities that resulted in the greatest benefit in performance based on test data covering a range of intensities, shot sizes, and other variables.
