In situ annealing and computation study of cube texture development in a commercial aluminum alloy
Abstract The aim of this study was to identify the physical processes of nucleation and growth of cube grains by means of in situ annealing experiments. The calculated nucleation site density at cube bands was found not to be sufficient for a correct computational prediction of the cube recrystallization texture. Growth competition at an early stage of recrystallization has to be taken into account for a better agreement between model and experiment, which necessitates a sufficiently refined grid resolution in discrete computer models of recrystallization. Accounting for these dependencies yields an excellent prediction of both the cube component in the recrystallization texture and the grain size distribution. The contribution of cube nucleation apart from cube bands to the cube recrystallization texture was found to be negligible.
