| Abstract: | Comparing with single-stage aging, influence of stepped aging process on stress corrosion resistance was studied in 2091 Al-Li alloy by using slow strain rate tension and three points bending speciments. Experimental results show that stepped aging process not only enhances mechanical properties but also improves resistance against stress corrosion of the alloy. Mechanism of stress corrosion in the Al-Li alloy was discussed in this paper. |
