The effects of cryorolling with a strain of e~2 at liquid nitrogen temperature and further natural and/or artificial aging on the resistance to intergranular corrosion (IGC) of preliminary quenched D16 aluminum alloy have been investigated. It is shown that cryorolling increases IGC depth and intensity for both T4 and T6 conventionally aged alloy conditions. Structure and phase factors of the alloy IGC after processing with and without cryodeformation are discussed in detail.
