The fracture behavior of a particle-contained, fully recrystallized Al-4mass%Cu alloy was investigated through in-situ tensile testing using a laboratory based multimodal X ray tomography approach. Diffraction contrast tomography was used to reconstruct the grain structure of the entire gauge length of the tensile sample before deformation. Additionally, absorption contrast tomography was employed not only to identify local particles breakage and void initiation but also to track local intragranular plastic strain development through a microstructure tracking method. The combination of these tomography techniques allowed revealing where and how fracture path develops. In this study, time-dependent damage evolution and strain development are analyzed in relation to the initial grain microstructures around the final fracture path. By this analysis, the effectiveness of multimodal X Ray tomography in laboratory based equipment for conducting multiscale microstructure analysis and for investigating complex fracture problems is demonstrated.
