| Abstract Scope |
Solid phase processes that induce beneficial microstructures also typically cause part-scale residual stresses. These stresses are often not a priority in process development studies, and the focus is on determining local mechanical properties through material characterization and testing on small cut samples. Nevertheless, residual stresses and the associated distortion must be considered because they could negatively affect the part properties. In this work, we utilize the electronic speckle pattern interferometry (ESPI) hole drilling technique to investigate the residual stress distributions from two kinds of solid phase processes, peening and friction stir processing, and for two aluminum alloys. This instrument's through-thickness stress measurements make it possible to relate stresses to distortion. A study of the effect of changing process parameters was also carried out. This work aims to incorporate residual stresses in understanding the process-part property relationships and optimize the development of solid phase processes. |
