Microstructural evolution during recrystallization in hot rolled Aluminum Alloy 1050

The evolution of texture as a function of recrystallization has been characterized for hot-rolled AA1050. Samples prepared from a hot rolled sheet were annealed isothermally for sufficient time to allow complete recrystallization. The spatial orientation variation within the deformed microstructure of nucleation, growth and orientations of recrystallized grains is examined. The microstructural variation and texture evolution in the samples is observed by automatic indexing of Electron Back Scatter Diffraction (EBSD) patterns in a Scanning Electron Microscope (SEM). The effect of deformation texture on the evolution and growth of various recrystallization texture components is also analyzed by EBSD. The analysis is aimed at obtaining a correlation between the deformation microstructure, texture development and recrystallization kinetics in the hot-rolled condition.
