摘　　要：文章总结了国内外Al-Zn-Mg-Cu系铝合金生产研究和实际应用的现状,并论述了热处理工艺对Al-Zn-Mg-Cu系铝合金微观组织与性能的影响。针对目前Al-Zn-Mg-Cu系铝合金实际制造过程中,为获得良好的抗应力腐蚀性能(SCC),往往以牺牲其强度为代价的问题,介绍了SCC的主要产生机理及Al-Zn-Mg-Cu系铝合金合金成分,微观组织以及热处理工艺对SCC行为的影响。This paper presents the current situation of production research and practical application of Al-Zn-Mg-Cu aluminum alloy in domestic and abroad,and discusses the effect of heat treatment process on microstructure and properties of Al-Zn-Mg-Cu aluminum alloy.At present,in the actual manufacturing process of Al-Zn-Mg-Cu aluminum alloy,in order to obtain good stress corrosion resistance(SCC),the strength is often sacrificed.Aiming at this problem,this paper introduces the main generation mechanism of SCC and the alloy composition of Al-Zn-Mg-Cu aluminum alloy and effect of microstructure and heat treatment on SCC behavior.
