Effect of Variation in Initial Crystallographic Texture of Aluminum Alloys on Residual Stress Stability in Fatigue Loading

, , &
Laser Shock Peening (LSP) improves the fatigue properties of new and damaged metallic components by introducing beneficial compressive stresses. The residual stress field that develop in the material after LSP and its behaviour in the service life depends on the microstructure and elastic-plastic properties of the material. The engineering components with variable microstructure and crystallographic texture when treated with LSP develop different residual stresses. In this experiment, we will underpin the deformation mechanism of aerospace...
