Abstract The effects of annealing temperature on the mechanical properties, corrosion resistance, and microstructure of 5A06 aluminum alloy cold-rolled sheet were studied by tensile testing, intergranular corrosion testing, optical microstructure observation, and electron backscatter diffraction (EBSD) analysis. The research results show that for 5A06 aluminum alloy cold-rolled sheets used in special equipment, when the annealing temperature is below 120 ℃, it's the stabilization annealing stage, and the intergranular corrosion resistance of the alloy is slightly improved. The annealing temperature within the range of 150 to 240 ℃ is the recovery treatment stage, during which the intergranular corrosion resistance of the alloy sharply decreases. The annealing temperature within the range of 270 to 330 ℃ is the recrystallization stage of the alloy, during which the β (Al₃Mg₂) phase undergoes dissolution, and the intergranular corrosion resistance of the alloy is rapidly improved, with mechanical properties tending towards the fully annealed state; The annealing temperature within the range of 360 to 540 ℃ is the recrystallization growth stage of the alloy. When the annealing temperature exceeds 540 ℃, the grain coarsening of the alloy is severe, and the mechanical and corrosion properties of the alloy deteriorate. The optimal stabilization annealing temperature range is 90 to 120 ℃, and the optimal O-state annealing temperature is 330 ℃. Overburning occurs when the annealing temperature is higher than 540 ℃.
