Particle stimulated nucleation is expected to be the dominating nucleation mechanism in many industrially relevant particle-containing aluminum alloys. However, most recrystallization characterizations have been carried out in 2D by microscopy. The aim of this work is to quantify particle stimulated nucleation in 3D in the bulk of an AA5182 alloy sample cold rolled to 75% reduction in thickness by two complementary experimental techniques. High-resolution synchrotron Laue micro-diffraction is used to map the spatial distribution of recrystallisation nuclei, while laboratory X-ray absorption contrast tomography is used to reveal second phase particles. Based on these multimodal 3D characterization results, the effects of particles of different chemical composition and size on the nucleation behavior are quantified. It is found that 73 % of the nuclei are particle stimulated when considering both Fe- and Mg-rich particles. It is furthermore shown that it is possible to index the Fe-based particles from the synchrotron X-ray Laue micro-diffraction patterns, and to extract residual stress information in both the recrystallized grains and the indexed particles. Effects of residual stress on nucleation is thus finally discussed.
