      • Abstract
    • The four points bending fatigue test was applied to A713 cast aluminum alloy by a material tester, and the curves of the density and strength of fatigue weakest link of the alloy were obtained by a new method of evaluating fatigue property. The results show that the fatigue strength of A713 cast aluminum alloy obtained by this method was 94.5 MPa. The fatigue weakest link density corresponded with Weibull distribution equation, and the fatigue weakest link strength was maximum when the stress level was 65%. Compared with pore size distribution, the distribution of density and strength of fatigue weakest link was more suitable to be used as the evaluation index of fatigue property of materials.
