Aiming　at　the　agglomeration　in　a　large　area　of　TiB2　particle　reinforced　aluminum　matrix　composites，TiB2/　A356　aluminum　matrix　composites　were　prepared　by　self-designed　multi-layered　electromagnetic　stirring　equipment，and　effects　of　multi-layered　electromagnetic　stirring　process（starting　stirring　temperature，stirring　time）on　microstructure　of　TiB2/A356　were　investigated　combined　with　the　testing　means　of　OM，SEM，EDS，etc.　The　results　indicate　that　with　the　starting　stirring　temperature　of　640　℃　and　stirring　time　of　30　s，effects　of　multi-layered　electromagnetic　stirring　process　on　dispersion　of　TiB2　agglomerates　are　desirable，and　the　size　of　agglomerates　is　5～10　μm.　The　multi-layered　electromagnetic　stirring　process　can　enhance　the　convection　between　the　melts，refine　α-Al　phase，and　break　TiB2　particle　agglomerates，improving　the　agglomeration　phenomenon　of　TiB2　particles.　©　2025　Journal　Office　of　Special　Casting　and　Nonferrous　Alloys.　All　rights　reserved.
