Research Progress of High-strength Corrosion Resistant Aluminum Alloys

The studies on high strength corrosion resistant aluminum alloys in recent years are reviewed.Several representative types of aluminum alloys are discussed with the focus on alloy composition and heat treatments.The influence of common trace elements on alloy performance is summarized and the mechanisms are discussed.New research techniques for relevant studies are also introduced.It is pointed out that the impact of quench rate and natural aging is not yet well understood and the micro-corrosion and stress corrosion cracking of the alloys need further investigation.
