Abstract
In the present paper, the impact of exfoliation corrosion (EFC) of 2024 and 5083 aluminum alloys on the residual mechanical properties was investigated. Tensile test had been carried out on pre-corroded specimens, exposed to laboratory accelerated exfoliation corrosion solution. The analysis suggests that exfoliation exposure leads to decrease the mechanical properties of all materials. The effects of the grain boundary character distribution and precipitates on corrosion are discussed on the basis of experimental observations by Scanning Electron Microscope SEM combined with Energy Dispersive Spectroscopy EDS analysis.
