Abstract:
The effect of shot peening on 7055-T77 aluminum alloy has been investigated. 7055-T77 is a high strength alloy with microstructure of coarse grains and a pronounced
metallurgical texture, both resulting from its thermomechanical processing. Considerable improvement of fatigue strength was achieved with the changes of microstructure and
the introduction of compressive residual stresses via shot peening. An x-ray diffraction photographic method was found very useful to measure the depth of the shot peening
plastic deformation layer which otherwise is very difficult to measure by customary diffraction methods because of the microstructure and texture..
Keywords: shot peening; texture, fatigue, residual stresses
