Abstract:  
Reprinted from ADVANCED MATERIALS & PROCESSES, June 1993; ASM International, Materials Park, Ohio Shot peening is a method of cold working in which compressive forces are induced in the surface layers of metallic parts by the impingement of a stream of shot. These compressive forces enhance fatigue strength by offsetting the "stretching action" of applied tensile stresses. Therefore, either higher loads can be allowed with the same life, or the same loads can result in longer life.
