The influence of texture and GBCD on stress corrosion and intergranular corrosion in 2024 aluminum alloy

摘要

The recrystallization texture, grain boundary character distribution (GBCD) and their influence on the stress corrosion cracking and intergranular corrosion of 2024 aluminum alloy were investigated. Results showed that the texture of Specimen Al is characterized by the retained cold-rolling texture; while Specimen A3 has strong recrystallized cube texture and high frequencies of CSL grain boundaries (especially ∑7), which shows high stress corrosion and intergranular corrosion resistance.
