Abstract:  
Over the years many articles and discussions have centered on the merits of controlled shot peening. Some of these discussions refer to the continuing progress being made on understanding the metallurgy at the surface of the part and in the sub-layer. As the technology available to analyze the results of our peening effort evolves, we tend to focus on factors such as microstructure, X-Ray diffraction, shot shape, shot hardness, part distortion and stress analysis to name a few. All of the above are very significant and necessary studies, but what about the novice shot peener or the company that may have recently obtained its first shot peening machine? Highly technical discussions can be confusing and intimidating for those who have just entered the field of shot peening.
