Abstract
Numerical modeling of hot rolling 6061 aluminum alloy was performed in order to predict state variables: temperature, strain, strain rate, and stress. This was achieved with the finite element modeling package DEFORM 2-D. The state variables were used in a dynamic recrystallization (DRX) model that incorporates both continuous dynamic recrystallization (CDRX) and geometric dynamic recrystallization (GDRX) to predict grain structure evolution. The performed simulation was verified by experimental torsion tests and roll tests from literature. The objective of the present work is to link state variables with the prediction of grain structure evolution.
