11. Estudo do comportamento de corrosão dos intermetálicos presentes na liga AA 2024-T3, por meio de técnicas de microscopia associada a técnicas eletroquímicas / INVESTIGATION ON THE CORROSION BEHAVIOUR OF THE INTERMETALLICS IN THE AA 2024-T3 ALLOY BY MICROSCOPY ASSOCIATED TO ELECTROCHEMICAL TECHNIQUES.
The AA2024-T3 aluminium alloy is largely used in the aerospace industry. It has high mechanical properties due to the presence of alloying elements, mainly copper, that form finely distributed precipitates coherent with the matrix, during controlled aging treatment. However, during this process, large intermetallics (IMs) are also formed with composition and
