Abstract Scope |
It is well known that significant microstructural variations develop on several length scales in metals during plastic deformation, and that these variations affect subsequent recrystallization. In the present talk the recrystallization characteristics - i.e. active nucleation sites and boundary migration rates, are used to shed further light on the deformation microstructure heterogeneities. The nucleation and growth of recrystallizing grains are characterized in 4D by synchrotron and laboratory X-ray diffraction as well as by absorption contrast tomography in commercial aluminum AA 5182, as well as in pure aluminum tricrystals. The deformation heterogeneities of primary importance for recrystallization are pinpointed and the underlying formation mechanisms are discussed. Finally, the latest results related to improvement of the spatial resolution in microstructural mapping using laboratory X-ray diffraction are presented; now grains below 5um can be mapped in home laboratories. |
