Aluminum alloys are one of the most commonly used precipitation-strengthened structural alloys in aerospace and automotive applications. The high strength of these alloys can be attributed to complex dispersions of nanoscale precipitates, which impart resistance to deformation and promote dislocation storage. Linking in situ nanoscale deformation behavior in such alloys to their non-destructively characterized 3D microstructure can have seminal implications in furthering our understanding of structure-property correlation in these alloys. This would pave way for microstructural design to improve specific mechanical properties such as fracture toughness, fatigue resistance, etc. In this study, a combination of Transmission X-ray Microscopy (TXM) and Micromechanical testing has been employed to monitor initiation and evolution of damage at the nanoscale in real time. Coupling this with techniques like EBSD and Transmission Electron Microscopy (TEM), has allowed us to establish a comprehensive understanding of deformation behavior in these alloys.
