Abstract: Al₂O₃ short fiber/Al-Si alloy matrix composite was prepared by squeeze casting. Solidifying structures of the composite were investigated. Results showed that primary silicon and eutectic silicon grains in the composite are obviously refined.

Key words: composite; short fiber; Al-Si alloy; solidifying; structures; squeeze; casting
