Hot and cold rolling of aluminum sheet (TP B1)
The objective of the study was the complete through-process modeling of crystallographic texture evolution during aluminum sheet production. The process was modeled from the hot rolling process through the final annealing of the samples by applying various models. The deformation texture (GIA) model was coupled to a statistical analytical recrystallization texture (StaRT) model. The nucleation spectra for recrystallization were modeled with ReNuc, a collection of several submodels describing different nucleation mechanisms. A finite element model incorporating dislocation density-based work hardening as well as texture served as a process model to describe the macroscopic production parameters based on microstructural information. The behavior so modeled was validated by comparison with experimental data. This comparison has confirmed the good quality of prediction of the models used.
