Corrosion Fatigue of Cu and Cu 7.8% Al
Abstract
Transmission electron microscopy of pure copper exposed to air and to corrosive solutions under cyclic stresses shows that corrosion effectively 'softens' metal surfaces by destroying the dislocation cell structure and preventing its reformation, thus resulting in accelerated slip. Additionally the preferential corrosion of surface slip offsets and grain boundaries results in grooving of these areas and rapid intergranular crack initiation and similarly studies of Cu 7.8% Al alloy single crystals shows corrosion to be specifically associated with surface slip offsets.
