Abstract

High strength aluminum alloys have been widely used in marine and aircraft industries due to the attractive combined properties, such as low density, high yield stress, ductility, and fatigue resistance. However, these series alloys are susceptible to stress corrosion cracking (SCC) in sea environment which substantially restricts their further development and application. The mechanism of SCC in the high strength aluminum series alloy is generally attributed to anodic dissolution of the grain boundary region exacerbated by the tensile stress. In this article reviewed the stress corrosion cracking high strength series aluminum alloy. An extensive failure occurred in the aircraft industry, and what kind of mechanism led to initiate and propagate the stress corrosion cracks. The article covered most of the results of stress corrosion crack test with 7XXX series of aluminium alloys that have been obtained to date with fracture mechanics and stress corrosion crack growth rate measurement with the results from various testing specimens. The major part of the article is reviewed the SCC behavior of high strength aluminium alloys and it is still in a research area of high interest due to the favorable behavior in the aircraft industry. The article brings out the general understanding of the SCC mechanism and the critical metallurgical aspects and issues affecting the SCC behavior of high strength heat treatable alloy. © 2015 Elsevier B.V., All rights reserved.
