Shot peening is a mechanical surface treatment that is used to improve material performance. The velocity of the shots is a significant parameter of the shot peening process, but it is not used as a controlled parameter by the shot peening industry.

Experimental investigations into shot peened ductile steel have been carried out, applying three surface finishing conditions: as machined, standard shot peening using 100% coverage and severe shot peening with 1000% coverage (high exposure time). Th

During low cycle fatigue of shot-peened parts, the competition between the compressive residual stresses and the hardening damage, both of which are produced by cumulated plastic strains, is of major importance for lifetime improvement. In order to t

A model has been developed by Guechichi et al. and improved by Khabou et al. to predict residual stresses and plastic deformation induced by shot peening in metallic parts. The major controlling factors were taken into account. The effect of the tang

Residual stresses induced by two shot peening conditions in nickel base superalloy Inconel 718 and their relaxation after different exposure times (10 and 100 h) at 600 and 650°C were evaluated by an X-ray diffraction technique. The behaviour of str
