N2 - Four-point bend fatigue tests were conducted on an AA2524 T34 Al alloy, along the rolling direction at room temperature and frequency of 15 Hz, R = 0.1, in air. It was found that the fatigue limit of the alloy was 87% of its yield strength, almost doubled that of its predecessor, an AA2024 Al alloy. Cracks were initiated predominantly at coarse particles but occasionally at grain boundaries on the surface. Crack propagation was in a crystallographic form. The coarse particles in the AA2524 Alloy were much less than those in an AA2024 alloy, which contributed significantly to the superior fatigue properties in this alloy.
