Reversible twinning in pure aluminum.
Twinning in metals is normally a permanent plastic deformation mechanism. Here we report reversible twinning in high stacking fault energy (SFE) aluminum. Twinning and spontaneous detwinning at the crack tip have been captured in situ during tensile straining under a transmission electron microscope. Both the in situ observation and the molecular dynamics simulations reveal a two-stage detwinni...
متن کاملCORROSION BEHAVIOR OF 6063 ALUMINUM ALLOY IN ETHYLENE GLYCOL-WATER SOLUTION
The electrochemical behavior of 6063 aluminum alloy in ethylene glycol-water mixture was investigated by polarization curves and AC impedance measurements (EIS). The results obtained from polarization curves showed that corrosion rate decreased with increasing ethylene glycol concentration. EIS data showed the decrease in the interface capacitance which caused by adsorption of ethylene glycol ...

متن کاملStress-Assisted Corrosion of Aluminum 6061 in Basic Solution
Caustic stress corrosion cracking has only been superficially examined in aluminum alloys. In caustic (basic) environments, the inherent, protective oxide layer becomes soluble on aluminum and allows for further degradation. The purpose of this study is to observe the effect of a strong base solution (sodium, hydroxide, sodium hypochlorite, sodium silicate, pH ~12) on the strength and stress-st...
متن کاملCharacterization of pitting corrosion in aluminum films by light scattering
We report a detailed study of the morphology of pits formed by corrosion of aluminum thin films using an in-plane light scattering technique. We show that the corrosion front of the Al thin film can be treated as a quasi-two-level random rough surface. Based on an elastic diffraction theory, we are able to determine the average depth, the area, and the density of pits, as well as the fractal di...
