    Notes: Aluminum alloys are increasingly used in automotive and aeronautic applications toproduce high performance, lightweight parts. Among the reasons for this, is the emergence of highintegrity processes (HIP), which widens the field of application for cast aluminum alloys. In fact,metallurgical quality and consistency that characterize components produced by HIP are necessaryfor critical safety components. In addition to attaining maximum strength, critical safetycomponents need to be ductile and resistant to cyclic loading. According to the North American DieCasting Association, rheocasting is a high integrity process capable of producing parts with fewerdefects than conventional casting process. Rheocast components are known to have bettermechanical properties than permanent mold castings. Moreover, they can be heat-treated which isimpractical in the case of classical die cast components. However, the fatigue behavior of rheocastaluminum alloys has been investigated since about 2000 and few results have been published onthis subject. This paper reviews the studies of fatigue behavior of aluminum semi-solid castcomponents. Published experimental results on high cycle fatigue resistance (S-N diagrams), longcrack propagation, crack closure effects and short crack particularities are presented
