The effect of deformation on the stress–corrosion cracking (SCC) of Al–Zn–Mg–Cu alloys is studied by slow strain rate technique (SSRT) and bolt‐loaded double cantilever beam (DCB) tests. Results show that with the deformation increasing, the undissolved particles and subgrain size decrease whereas the fraction of recrystallization increases after solution treatment. The susceptibility to SCC by SSRT and DCB tests varies on different deformation amount alloy, in which cause is discussed.
