This paper investigates the homogenization annealing of 8021 aluminum alloy after a single deformation at different temperatures. The microstructures of the annealed sheets were characterized using techniques such as EDS, BSE, and SEM. The results show that after homogenization annealing, the tensile strength and yield strength of the material significantly decreased, while the elongation rate markedly improved. Furthermore, as the homogenization temperature increased, the grain size of the final sheets gradually decreased, and the strength also increased with the rise in homogenization temperature. These findings provide important experimental insights for optimizing the heat treatment process of 8021 aluminum alloy.
