The service properties of materials strongly depend on the chemical composition, as well as their processing conditions. The specific applications and the optimization of thermal and thermo-mechanical processes, respectively, enable both, to save processes and to treat new alloy variants, as well as to realize materials with special properties. The numerical simulation of metal processing, coupled with the modelling of the structural evolution allows to reduce time and cost expensive tests at lab and industrial scale. Here, multi-scale modelling is an appropriate means to describe the development of the nano, micro and macro structure and, hence, to determine the local materials properties.

Abstract: During thermomechanical processing of AA6082 several physical mechanisms occur simultaneously. Specially at large strains, continuous dynamic recrystallization (CRDX) have shown to be the restoration mechanism that follows dynamic recovery at high temperatures. In this work, we propose a microstructure model to account for the evolution of dislocation densities, misorientation distributions, fractions of high and low angle grain boundaries, and grain and subgrain sizes. The microstructure evolution is coupled with constitutive equations to predict the flow stresses depending on strain, strain rate and temperature. Flow curves, obtained through hot torsion tests and microstructure characterization with SEM-EBSD analysis of non-deformed and deformed samples are used to refine and validate the physical based model.
