“…The high impedance values (|Z|) in the Bode impedance plots in the low-frequency region indicate that the alloy has a large polarization resistance. [30,31] From the Bode impedance plots of Al-6Mg alloy as illustrated in Figure 8b, it can be seen that the impedance value (|Z|) in the low-frequency range decreases as the deformation increases. The evolution is consistent with the change law of the capacitive arc diameter.…”

“…Due to the shearing deformation and large local strains associated with ECAP 4 passes, the distribution of the T phase along the grain boundary is destroyed and redistribution occurs, resulting in a larger spacing of the T phase along the grain boundary and enhanced corrosion resistance. [31] According to the relevant studies on Al alloys, these alloys with multipass ECAP processing that contains second phases or precipitates, exhibit superior corrosion resistance due to the redistribution of precipitates along the grain boundaries. [7][8][9]19] Above all, a schematic microstructure evolution sketch is used to explain the electrochemical behavior of Al-6Mg and Al-6Mg-1Zn alloys subjected to the different passes of ECAP, as shown in Figure 10.…”

Al-Mg series alloys have been widely used as structural materials in the automobile, electronic device, and shipbuilding industries due to their high specific strength, good heat dissipation, and formability. [1] Recently, the mechanical properties of Al-Mg alloys have been improved further through a combination strategy of increasing the solute Mg content, severe plastic deformation processing, and heat treatment, which can alleviate the contradiction between high strength and ductility. [2,3] For instance, Zha et al. processed an Al-7Mg alloy through equal channel angular pressing (ECAP) combined with interpass annealing, which simultaneously resulted in high strength (UTS % 507 MPa) and excellent ductility (uniform elongation > %11%). [4] In addition, because Mg has the solubility limit of %1 at% in Al matrix at room temperature, the β (Al 3 Mg 2 ) phase precipitates along grain boundaries (GBs) of Al-Mg alloys with high Mg content. [5][6][7] However, because the β phase has a higher active potential than the Al matrix in Al-Mg alloys, it acts as an anode, severely deteriorating the corrosion resistance. [8] Moreover, based on the previous experimental results of Al-Mg alloys, [9][10][11] the high Mg content and severe plastic deformation processing aided the β-phase precipitation, which deteriorated the corrosion performance and mechanical properties.Alloying, an effective method to improve the mechanical properties and corrosion resistance of Al-Mg alloys, has received extensive attention. For example, Gao et al. [12][13][14] clarified the combined effects of Al 6 Mn phases and Al 3 Sc dispersoids on microstructure evolution, strength enhancement, and outstanding ductility of the extruded Al-Mg alloys. In addition, several studies have been conducted to investigate the effect of additional alloying additions on the nucleation and growth of β-phase particles of Al-Mg alloys. [15][16][17] The effect of each alloying addition on β-phase evolution was different. In general, there are mainly two approaches to enhance the corrosion resistance of Al-Mg alloys by adding alloying elements. One approach is to suppress the nucleation of β phase. For instance, the Al-5.8Mg-0.4Mn

“…The corrosion behaviors of Al-Li alloys are currently being widely investigated. And the results show that the corrosion behaviors of Al-Li alloys are greatly influenced by their heat treatment (Jiang et al, 2020;Chen et al, 2021;Kuang et al, 2021), precipitates (Zhu et al, 2020;Xu et al, 2022), surface abrasion (Liu et al, 2018), and corrosion environment (Qin et al, 2021;Jiang et al, 2022;Guérin et al, 2015).…”

“…Holes, cracks and dents are the most common causes of tensile strength and fatigue life loss in the fuselage skin panels (Li et al, 2015a). The investigations on the corrosion of Al-Li alloys show that corrosion pits (holes on the surface) often form during the corrosion (Kuang et al, 2021;Zhu et al, 2020;Xu et al, 2022;Liu et al, 2018;Qin et al, 2021;Jiang et al, 2022;Guérin et al, 2015). Therefore, study on the relationship between corrosion pit and residual strength of Al-Li alloys is meaningful to extend their applications.…”

The structural safety and service life of civil aircraft can be decreased by corrosion damage to their aluminum components caused by long-term service in corrosive conditions. In this work, the effect of heat treatment on corrosion behavior and tensile strength was systematically analyzed for 2060 Al-Li alloy immersed in 3.5 wt% NaCl solution for different corrosion times. The results show that the corrosion depths of the 2060-T4 and 2060-T6 Al-Li alloys immersed for 720 h are 85 and 93 μm, respectively. The ultimate tensile strengths of 2060-T4 and 2060-T6 Al-Li alloys immersed for 720 h were reduced by 5.8 and 6.4%, respectively. Linear relationships between tensile strength and the corrosion depths of 2060-T4 and 2060-T6 Al-Li alloys were established as σres=486−0.33h and σres=547−0.35h respectively.
