Abstract
By high temperature compression experiment, true stress vs true strain curve of 6082 aluminium alloy are obtained at the temperature 460°C -560°C and the strain rate 0.01s-1-10s-1. The effects of deformation temperature and strain rate on the grain evolution are investigated; Critical strain of dynamic recrystallization of 6082 aluminium alloy model is obtained. The results show lower strain rates are beneficial to increase the volume fraction of recrystallization, the average grain size is coarse; High strain rates are beneficial to refine average grain size, the volume fraction of dynamic recrystallization is less than that in low strain rates. High temperature cause coarse grains. Dynamic recrystallization grain evolution model and model of DRX fraction can effectively predict recrystallization grain size and recrystallization fraction of 6082 aluminium alloy thermal deformation.
