Abstract:  
Peening is a very useful process for extending the service life of a large number of metallic components. Its benefits can only be maximised through an understanding of the principles that are involved in shot peening. Presents a comprehensive account of these principles, overing basic mechanics, peening media, residual stress distributions, coverage and equipment. The essential residual stress requirement is to induce a surface layer of compressively stressed material. Proper control of peening parameters is needed in order to optimize the residual stress profile for specific components. Presents and discusses the several factors that influence the residual stress profile.
