The corrosion fatigue behavior of notched 2024-T351 aluminum
Notched tensile tests and notched fatigue tests were performed at room temperature to study the corrosion fatigue behavior of aluminum alloy 2024-T351 in 3% salt solution. Notched characteristics of aluminum alloy 2024-T351 were found to be the same as those of other high strength aluminum alloys. …
