The critical peening parameters for improving fatigue life include exposure time, shot flow rate, the distance between the shot-throwing station (blast wheel or nozzle) and the work surface, shot diameter, and shot hardness. The objective of the present work is to investigate the effects of these controlling parameters of shot peening on the material properties of the product to be treated. By analyzing how each parameter influences residual stress distribution, surface roughness, and microstructural changes, this study aims to optimize the shot peening process for enhanced fatigue performance
