摘 要：The effect of magnesium on the microstructures of A356 aluminum alloy in as-cast and semi-solid conditions was investigated.The result showed that magnesium refined the size of primary a（Al） phase and eutectic silicon.Magnesium also modified considerably the eutectic silicon and decreased the size of globular a（Al）solid phase in the semi-solid processed alloy.℃oarsening rate of the solid a（Al） phase during partial remelting at semi-solid temperature decreased by adding magnesium,probably due to the decrease of both the solide liquid interfacial energy and inter-diffusion coefficient of solute atoms.
