Abstract: The formation of a special Si-rich layer on the periphery of Al-Si eutectic alloy specimen during directional solidification in rotary electromagnetic field has been investigated.This layer seems due to the migration of some Si grains onto the crucible wall,then stagnating and coarsening further.

Key words: Al-Si eutectic alloy, directional solidification
