Abstract ABAQUS numerical simulations combined with hot rolling experiments were conducted to investigate the effects of rolling pass number and deformation on the microstructural evolution of 6016 aluminum alloy during hot rolling. The results reveal that both of them significantly influence dynamic recrystallization (DRX) behavior and grain refinement. At a rolling temperature of 460 ℃, the deformation increased from 35.1% to 62.2%, and the DRX grain size reduced from 10.1 μm to 4.8 μm, while the DRX volume fraction increased from 5.8% to 11.6%. The electron backscatter diffraction (EBSD) analysis shows that dynamic recovery and shear stress during hot rolling generate numerous sub-grain boundaries and shear bands, which promote grain refinement. Experimental results demonstrate that the simulation results are in good agreement with the experimental observations, with an average prediction error of 14.8%. These findings demonstrate the reliability of the numerical model in predicting the overall microstructural evolution of the 6016 aluminum alloy during hot rolling.
