Abstract:A research has been conducted on the influence of five factors, namely deformation, pre-recovery temperature, pre-recovery time, annealing temperature, and annealing time, on the mechanical and corrosion properties of 2024 aluminum alloy by adopting the orthogonal experimental method. The results show that each factor has a significant impact on the material properties, with annealing temperature being the most significant factor affecting the mechanical properties, while deformation and annealing time being the most and least significant factors affecting corrosion performance, respectively. The optimal deformation annealing process obtained through orthogonal optimization is as follows: with its deformation variable being 80%, a pre-recovery of alloy for 120 minutes at 220 ℃ with an annealing for 10 minutes at 320℃. The alloy obtained under this process is characterized with good comprehensive properties, with the microhardness, tensile strength, yield strength, elongation, corrosion depth, Rp and Icorr of the sample being 74.49 HV, 217.17 MPa, 185.84 MPa, 13.53%, 55.4 μm, 3 885.6 Ω·cm-2 and 9.42E-06 A·cm-2, respectively.
