| Abstract: | In this paper, the effects of melting temperature and the temperature of metal plate on the solidification structure of Al-16Si alloy have been investigated in detail. An ultra-low-temperature copper tube was used to force undercooling of the melt, while metal plates at different temperatures were employed to achieve temperature-controlled solidification. The results show that when the melting temperature is 800°C, the precipitation of primary Si could be completely inhibited by means of forced melt undercooling, and the eutectic structure composed of fine rod and thin sheet shapes could be obtained by solidifying on the metal plate at room temperature. When the forced undercooling alloy melt is poured onto the metal plate at 527°C and solidified on its surface, the pseudo-eutectic solidification microstructure could be obtained.
