Abstract:  
100% coverage: Is it necessary for all shot peening applications? Or is the work needed to achieve it, in some instances, a waste of time and media? Or worse yet, does it compromise one of the very benefits we hope to achieve through shot peening-the termal stability of the compressive layer?
