Keywords：A201 Aluminum Alloy，Local Solidification Time，Dendrite Cell Size

Abstract：A201 aluminum alloy plate castings with systematic change in the riser size，together with variation of thickness and length，were cast in different kinds of molds to find out the in fluence of local solidification time on the dendrite cell size. The sand molds with end chill for the plate castings were made of 100% silica sand. The dendrite cell size of A201 aluminum alloy plate castings is governed by the cooing rate. The longer the local solidification time，the larger the dendrite cell size was found in this study.
