Abstract
To understand the formation of the deformation substructure and its evolution during annealing to produce unique microstructures and textures in aluminum alloys, the development and coupling of physically based models spanning different length scales is necessary. Under hot deformation conditions, the deformation substructure is a collection of cells/subgrains of different sizes and orientations. Recrystallization following hot deformation occurs by the heterogeneous evolution of the subgrain structure, the kinetics of which is controlled by variations in driving forces and boundary properties at the microstructural length scale. This article describes a mesoscale approach for modeling the microstructure and texture evolution during recrystallization following hot deformation. A Monte Carlo simulation technique is used to evolve the substructure and texture during recrystallization. The simulations are applied to the deformation and recrystallization of aluminum bicrystals with specific combinations of crystallographic orientations. The simulation result are compared with experimental results.
