Abstract
In order to understand the stress corrosion behavior of super-high strength aluminum alloys by spray forming, different aluminum alloys by different heat treatment was made. The results showed that the alloy with peak aging has the most sensitive stress corrosion cracking, the crack can even be seen using eyes; the alloys with two step aging were better than one step aging alloys, the alloys has not been found stress corrosion cracking.
