Abstract
Shot Peening is part of the family of blasting processes widely used in surface treatment of parts and structures in the industrial field, being one of the most effective techniques in increasing resistance to fatigue. The Shot Peening process is one of the main steps in the process of producing components subjected to cyclic stresses and, consequently, failure due to fatigue. In this way, this work has as general objective to study the effects induced by the shot peening process in the relation between the microhardness and the residual stress steel JIS SCM 420 HV2. It was observed that the shot peening causes an increase of the microhardness to a depth of 0.06mm, just as the peaks of compressive residual tension were obtained at a distance of 0.03mm.
