This paper investigated the effect of shot peening on strength and corrosion properties 6082-T651 aluminium alloy. The microstructure, surface roughness, microhardness, residual stresses, behaviour were compared with those untreated Cracks delaminations in layer could only be seen treated specimens at a working pressure 4 bar 8 bar, while no such was observed 1.6 bar. roughness increased more t...
