Niku-Lari ABSTRACT Variations in machining parameters that are employed in traditional as well as nontraditional metal cutting operations can have a profound effect on surface characteristics such as microstructure, residual stresses and surface sensitive mechanical properties, specifically fatigue and stress corrosion resistance. This paper presents the effects of shot peening, a commonly employed postmachining operation, on the surface sensitive properties of several aerospace materials.
