In this work, the effects of cooling rate on the microstructure and tensile strength of A356 wheels during solidification were studied. Four cooling methods, including air cooling, wind cooling and two different water coolings, were a used to control the cooling rate of spoke. Comparing with the air cooling and wind cooling, at higher water cooling rates, the iron phase appeared from the peritectic-type reaction, which transformed from the previous -Al5FeSi phase to -Al8Mg3FeSi6 phase. Besides, as cooling rate increased from 0.69 °C/s to 1.95 °C/s, the secondary dendritic arm spacing (SDAS) declined from 44.41 m to 31.86 m. The UTS and YS could reach 225.27Mpa and 143.02Mpa in the water cooling with the minimum water flow velocity (16L/h), respectively.
