Abstract Scope |
It is well-known that the driving force for recrystallization is the energy and thus the dislocations stored in the deformed matrix. It is however not known how the migration of the recrystallization boundary is affected by the specific geometrical arrangement of the dislocations. Such phenomena can not be characterized in 2D, full 3D mapping is needed. This is the purpose of the present work. A pure aluminium single crystal is cold rolled to 12% and nucleation is stimulated by a hardness indentation in one of the two crystals. Synchrotron X-rays using the 34-ID-E beamline at APS are used to map the deformation structure in 3D and to follow the growth of a nucleus formed at the hardness indent during 4 annealing steps. The boundary migration through the deformation microstructure is described and geometric as well as crystallographic interaction effects are discussed |
