摘要：
The fatigue behavior of 7075/T6 and 6061/T6 aluminum alloys in the very long life regime was investigated by using piezoelectric accelerated fatigue tests at 19.5 KHz. The mechanism of fatigue crack initiation and propagation by void formation and growth was identified using scanning electron microscopy (SEM).
