Abstract

Shot-peening is a surface mechanical treatment, widely used to treat metallic parts in the aerospace and automotive industries. This mechanical surface treatment should not be confused with other common applications of other peening treatments, oriented towards cleaning, preparation or surface finishing. Shot peening is a mechanical treatment used to improve the service life of metallic components, especially when they are submitted to cyclic loads. The effect of shot peening on the surface work hardening and residual stress profile of a 35NCD16 steel was studied in this work.
