Abstract:  
Shot peening is a mechanical process of hammering of surface of a metal with shot, carried typically, in a blast of air [1]. When applied over the surface of a metal with an intensity sufficient to cause plastic flow, shot peening has three major effects: it produces a residual compressive stress in the surface, and it produces a roughened surface [2]. The surface stresses are very effective in resisting stress corrosion cracking [3] and cavitation
