应力腐蚀开裂(SCC)是7000系铝合金在腐蚀环境中应用遇到的关键问题.本文重点讨论了热处理工艺以及外部环境对7000系铝合金SCC的影响;同时结合作者的研究,探讨了SCC机理,首次提出了"相变-Mg-H"理论;并展望了并这-研究领域的未来.
Stress corrosion cracking(SCC) is a key problem when 7000 series aluminum alloys are applied in corrosive environments. The effect of heat treatment technology and environmental factors on SCC sus-ceptibility of 7000 series aluminum alloy was discussed. SCC mechanism was discussed and a " phase transformation-Mg-H" theory was proposed firstly. The future trend of this research field was also prospec-ted.
