Fatigue behavior of A356 aluminum alloy for motorcycle rim was experimentally investigated based on T6 heat treatment and artificial aging. The high speed of 1,100 rpm from centrifugal casting was used in this study. The pouring temperature at 750 °C was employed and the preheated temperature at 250 °C was applied on the mold. The solution heat treatment of the sample was conducted for 4 hours at 540 o C before it immersed into the water for rapid cooling at room temperature. This step followed by natural aging treatment at 30 °C and artificial aging treatment at 150 °C, 175 °C, and 200 °C for 2 hours, respectively. It is found that increasing centrifugal casting speed into 1,100 rpm combined with heat treatment and artificial aging temperature can significantly increase not only its mechanical properties but also the fatigue life of motorcycle wheel made of A356 aluminum alloy. This experiment proved that the lowest fatigue crack growth rate obtained with this method was at temperature of 175°C.
