The automotive and aerospace sectors make extensive use of aluminum alloy (2024) because of its exceptional mechanical qualities and lightweight nature. This study investigates the alloy's corrosion behavior following ageing and quenching heat treatments. Two tests were conducted: 40 cycles of accelerated corrosion in a climate chamber and immersion in a 5% NaCl salt solution for up to 1200 h. Following the corrosion tests, microscopic examination demonstrated the development of pitting. The interaction of solids and liquids caused by hydroxyl salts causes alloys to dissolve. Heat treatment plays a key role in modifying the microstructure of 2024 alloys, which has a direct impact on their corrosion resistance. In corrosion tests carried out on AA2024 alloy, it was observed that various heat treatments, such as quenching and ageing, lead to significant changes in the alloy's microstructure. These changes influence the distribution and morphology of precipitates, which in turn affect the alloy's reactivity with its environment.
