Abstract

Cooling slopes (CS) are the novel technique in the casting process, it suitable applied in the various alloys to modify the microstructure and mechanical properties. In the present work, the cooling slope has been designed and applied in the aluminum-silicon alloys. The effect of CS plate angle on microstructure and mechanical properties of aluminum alloy were investigated. The results suggested that the CS influenced the morphologies of materials which is correspond with the mechanical properties change.

Keywords: aluminum-si alloy sloping plate microstructure hardness
