Summary:

AbstractHardened steel is the majorly used raw material for automotive components. In spite of its abundance, its application is limited due to low fatigue life in dynamic loading. Shot peening is one of the identified processes to improve the fatigue life of the ductile steel by inducing the work hardening and surface improvement. The process of shot peening involves the bombardment of shots on the component surface. As the process and technique, the shot size selection plays very important role in the fatigue life improvement as it alters the results substantially. Also during the process, shot size decreases due to the normal wear of the shots after hitting the component surface. As a result, there is always a ratio of various sizes of the shots involved in the process. Therefore it becomes imperative to control the shot size ratio for obtaining the required work hardening and possible fatigue life improvement. This paper explains the effects of shot size ratio on the durability life of a component and the process of shot size ratio selection
