Corrosion Resistance of Li-Al LDHs Film Modified by Methionine for 6063 Al Alloy in 3.5 wt.% NaCl Solution

CORROSION BEHAVIOUR OF Al-Li-Cu-Mg ALLOY 8090-T651

Improve sensitization and corrosion resistance of an Al-Mg alloy by optimization of grain boundaries

The sensitization and subsequent intergranular corrosion of Al-5.3 wt.% Mg alloy has been shown to be an important factor in stress corrosion cracking of Al-Mg alloys. Understanding sensitization requires the review of grain boundary character on the precipitation process which can assist in developing and designing alloys with improved corrosion resistance. This study shows that the degree of ...

Mechanical Equation of State in an Al-Li Alloy

Existence of plastic equation of state has been investigated by performing a series of load relaxation tests at various temperatures using an Al-Li alloy. A plastic equation of state is first developed from a simple kinetics consideration for a mechanical activation process of a leading dislocation piled up against grain boundaries. A series of load relaxation test has been conducted at tempera...

Yielding Phenomenon of an Al-3% Li Alloy

where the specimens are recovered but not recrystallized. This second type of yielding is characterized by a sharp yield drop and long yield elongation. A mechanism of the second type of yielding has not been investigated, but it is clear that the yielding phenomenon is not due to a simple effect of strain aging, because the specimens has recovered so that dislocation arrangements should have c...

CORROSION 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 ...
