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.

实验表明:当浇注温度接近液相线温度时,AlSi7Mg合金中的初生α-Al凝固成球状或粒状,晶粒细小,分布均匀;获得球状或粒状AlSi7Mg合金半固态坯料的最佳浇注温度为615℃;在接近液相线温度下浇注,较快的合金熔体冷却速度、浇注引起的合金熔体活动和大范围的同时凝固促使AlSi7Mg合金形成球状或粒状的初生α-Al组织。

The formation of secondary phase in the non-equilibrium peritectic reaction was observed by precise transmission electron microscopy analysis.
