摘要：

Semi-solid　A356　alloy　slurry　was　prepared　by　adding　RE　element　(Er)　and　weak　electromagnetic　stirring　method.　Microstructure　of　the　prepared　samples　was　investigated　by　OM　(optical　microscope),　SEM　(scanning　electron　microscope),　TEM　(transmission　electron　microscope)　and　EDS　(energy　dispersive　spectrometer),　and　microstructure　evolution　was　discussed.　The　results　show　that　with　0.　05%　Er　addition,　primary　α　phase　is　converted　from　rosette　structure　into　spherical　ones.　Grain　size　in　the　prepared　alloy　containing　Er　can　be　further　refined　with　weak　electromagnetic　stirring　at　625　°C,　obtaining　the　required　semi-solid　slurry.
