Notes:
RRA treatment was applied to a high-Zn, 7XXX alloy under development for aerospaceapplications. Microstructure of the alloy is studied at different stages of the 3-step ageing process,by Transmission Electron Microscopy, in order to understand the corresponding evolution ofmechanical and corrosion properties. The Compression Yield Strength at the end of the hightemperature step was found higher than at the end of the 1st step, contrary to the conventional RRAtreatment. After re-ageing, the final CYS turned out significantly higher than at the T6 temper of thealloy, while the material remained sensitive to exfoliation corrosion
