When the pouring temperature is close to the liquidus temperature of AlSi7Mgalloy, the primary α-Alin the billets of AlSi7Mg alloy solidifies into spherical or nodular grainswhich are small and distributed homogeneously. In order to obtain non-dendritic semi-solidbillets,the appropriate pouring temperature is 615℃. The faster cooling rate,the melt flowing and largersolidification region induced by the near liquidus pouring temperature promotes theformation of spherical or nodular primary α-Al.
