摘 要：<正>The structure evolution of the ZL109 alloy in the process of semi-solid squeeze casting and the mechanical properties of the components were investigated.The results show that（1）the eutectic silicon phase in original billets is refined in the low super-heat casting process;（2） the eutectic structure in billets starts to fuse and the crystals of the eutectic silicon phase are refined further and sphericized in the remelting process of billets;（3）in the semi-solid squeeze casting process,the sphericity of theαphase and the refining of the silicon phase occur,ow- ing to the friction between solid and liquid;（4）in the process of heat treatment,the eutecticαphase aggregates with the primaryαphase and the eutectic silicon pieces aggregate together.The elongation of the semi-solid component after heat treatment rises to 1.42%.
