Simulation of the texture evolution of aluminum alloys during primary static recrystallization using a cellular automaton approach
- RWTH Aachen (Germany). Inst. fuer Metallkunde und Metallphysik
A 3D model has been developed to simulate both primary static recrystallization and recovery of cold worked aluminum alloys. The model is based on a modified cellular automaton approach and incorporates the influence of crystallographic texture and microstructure in respect to both mechanisms mentioned above. The model takes into account oriented nucleation using an approach developed by Nes for aluminum alloys. The subsequent growth of the nuclei depends on the local stored energy of the deformed matrix (i.e. the driving pressure) and the misorientation between a growing nucleus and its surrounding matrix (i.e. the grain boundary mobility). This approach allows to model preferred growth of grains that exhibit maximum growth rate orientation relationship, e.g. for aluminum alloys a 40{degree}<111> relationship with the surrounding matrix. The model simulates kinetics, microstructure and texture development during heat treatment, discrete in time and space.
