Abstract

Mechanical properties and exfoliation corrosion behavior in Al-Cu-Mg alloy with various pre-strain percents were characterized in this study by means of hardness measurement, optical microscope, transmission electron microscope (TEM), x-ray diffraction (XRD), and electrochemical technique. The hardness of naturally aged alloy was significantly enhanced with increasing the pre-strain percents. The immersion tests and polarization measurements revealed that the pre-straining processing before natural aging reduced the resistance of the alloy to exfoliation corrosion (EXCO), which was mainly attributed to the increase of dislocations density and grain aspect ratio. The decrease of residual tensile stress may only play a minor role in the EXCO resistance.
