Abstract:

Shot peening is a method widely used to improve mechanical properties of materials. The improvement in mechanical properties such as surface hardness, fatigue strength, tensile strength, damping etc. are due to the induction of compressive residual stress in the metal parts. The residual compressive stress induced by shot peening is the function of material and mechanical conditions. Its beneficial effects are mainly due to the residual stress field caused by the plastic deformation of the surface layer of material resulting from multiple impacts of the shot, although strain hardening and grain distortion caused by the multiple impacts of the shot also play a role in the modified mechanical behaviour of the peened components. Due to several advantages shot peening has been in the focus of research persons for the purpose of increasing the properties of the materials. In the present paper, a review study has been done on the shot peening effects on different materials. This review will help the researchers and readers to better understand the several benefits and applications of shot peening. The present review of shot peening process is focused on the latest development and pushes the readers towards the on-going research in this classic process. The authors have not come across any such type of review which focuses mainly on shot peening process.
