| Abstract Scope |
Thermomechanical processing of metals introduces high dislocation densities, altering material properties through mechanisms such as work hardening. Non-destructive 3D mapping of deformation microstructures remains a challenge due to limitations in characterization tools. This study combines Dark-Field X-ray Microscopy (DFXM) and texture tomography (TT) to investigate deformation structures in 50% and 65% cold-rolled ferrite. DFXM enables non-destructive 3D mapping of intragranular deformation structures, resolving dislocation cells with elevated densities and misorientation values up to 5°, at a resolution of 100 nm. TT complements this by providing 3D grain orientation data, aligning grains relative to the rolling direction and bridging the effects of neighboring grains on deformation. These data are also validated with complementary Electron backscatter diffraction (EBSD) measurements. The combined approach reveals the evolution of intragranular deformation structures, cell size distributions, and strain hotspots as a function of deformation, advancing our understanding of plasticity and the interplay between local and global deformation behaviors. This framework offers critical insights into deformation mechanisms and recrystallization in metals. |
