Eutectic Al-Si composite in situ was fabricated under the condition of direct magnetic field. Eutectic segregate happened,which formed the enrichment layer of silicon in the cylindrical sample surface, and the thickness of the segregation layer grows with the increase of the magnetic induction intensity. Effect mechanism of the direct magnetic field on the microstructures' formation disciplinarian of composite in situ has been discussed.
