| Abstract: | In this paper, the factors that influence the fatigue properties of A356 cast alloys are summarized. The effect of the casting defect, eutectic silicon, SDAS, Fe-rich particles and closure mechanisms on the fatigue properties of A356 alloys is discussed in detail, and their impact mechanism is analyzed. At last, the methods which can improve the fatigue properties of A356 are discussed. |
