Abstract Scope |
Recrystallization governs the final microstructure of thermal processed metals and is thereby of high interest in both industry and research. However, most recrystallization experiments are carried out in 2D not fully describing the bulk 3D materials. In this study, the efficiency of particle stimulated nucleation (PSN) by large second phase particles in 75 % cold rolled AA5182 aluminum alloy is investigated by two different non-destructive high-resolution 3D techniques. Conventional absorption contrast tomography is used to reveal second phase particles, while the high resolution of Laue micro-diffraction is exploited to reveal recrystallized nuclei. Data registration between the two 3D volumes is performed by relating areas in Laue patterns with increased occurrence of un-indexed peaks with second phase particle positions in the tomography data. This registration methodology is discussed and the importance of PSN for the recrystallization of this aluminum alloy is quantified. |
