Abstract：

Al-20Si　alloy　was　prepared　by　electromagnetic　stirring　and　by　melt-blending　combining　with　electromagnetic　stirring,　respectively.　The　results　indicate　that　a　segregation　layer　can　be　observed　in　the　AlSi　alloy　prepared　by　electromagnetic　stirring,　in　which　the　size　of　primary　Si　phase　is　more　than　60pm,　while　coarse　primary　Si　segregation　occurred　in　edge　of　electromagnetic　stirred　A1-20Si　alloy　can　be　eliminated　and　size　of　primary　Si　phase　can　be　refined　to　less　than　16μm　after　combination　treatment　of　melt-blending　with　electromagnetic　stirring,　which　is　attributed　to　melt-blending　promoting　the　electromagnetic　stirring　effects　on　A1-20Si　alloy.
