%X The effect of cathodic polarization and welding procedure on stress cracking corrosion of 7A52 aluminum alloy was investigated by slow strain rate test.Fracture morphology was observed by stereo-microscope and SEM.The results showed that the stress cracking corrosion index of 7A52 aluminum alloy increases with cathodic polarization,thereby susceptibility to stress cracking corrosion increases.The stress cracking corrosion performance of the specimen prepared by friction stir welding is better than by metal ...
