N2 - The cast aluminum alloy A356 was studied to observe the effects of the eutectic silicon particles on its fatigue strength characteristics and the initiation and propagation of fatigue cracks. Two mechanisms of the initiation of the fatigue cracks were observed in the low-cycle fatigue regime, and only one in the high-cycle fatigue regime. A small fatigue life scatter was also found to be characteristics of the specimens of the alloys. Furthermore, the existence of a fatigue limit in the alloy is discussed.
