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...

Nondestructive evaluation of the prevailing compressive residual stress in the shallow subsurface layer of surface-treated metals is greatly complicated by the accompanying surface roughness and cold work. A high-precision laser-ultrasonic technique has been developed to study the feasibility of SAW dispersion spectroscopy for residual stress assessment on surface-treated metals in a wide frequ...
