摘要
Abstract
The effect of different pouring temperatures on the microstructures of AlSi7Mg alloy has been researched. When the pouring temperature is close to the liquidus temperature of AlSi7Mg alloy, the primary α-Al in the billets of AlSi7Mg alloy solidifies into spherical or nodular grains which are small and distributed homogeneously. In order to obtain non-dendritic semi-solid billets,the appropriate pouring temperature is 615℃. The faster cooling rate,the melt flowing and larger solidification region induced by the near liquidus pouring temperature promotes the formation of spherical or nodular primary α-Al.关键词
