- The present study discusses the effect of installation torque on the surface and subsurface deformations for thin-walled 7075 aluminum alloy. A FE model was constructed to predict the effect of torque-induced stresses on thin-walled geometry followed by experimentation. Detailed surface analysis was performed on 7075 aluminum in terms of superficial discontinuities, residual stresses, and grain deformations. The localized strain hardening resulting from increased dislocation density and its effect on surface microhardness was further studied using EBSD and micro indentation. The predicted surface level plastic strain of 25% was further validated with grain deformations measured using optical and scanning electron microscopy.
