Abstract
Modification of Al-Si cast alloys can be achieved in two different ways, namely by additions of certain eleınents or
with rapid cooling rate. Modifications of the Al-Si al1oys are carried out extensivcly in industry to improve the
mechanical properties, particularly ductility. In this study, the effects of antiınony addition.s and growth rate on the
ınicrostructure and eutectic morphology on the directionally solidified Al- 1 2.5°/o Si cutectic all oy has been
investigated. The results showed that antimony can be identified as a grain refıner. Over modification occurs in Al-
12.5 °/oSi alloy when modifier is present in the amount of 1 %Sb results in AISb compound.
