Abstract

Al-Si alloys are widely preferred in the casting industry due to their superior properties. When the coarse silicones are modified, the silicon structure is homogeneously dispersed and higher mechanical properties are achieved. Despite the continuous use of the modification process, there are uncertain points about the working mechanism. A full understanding of the mechanism will allow for more efficient processes to be developed. In this study, the ratio of % Eut/Al area and SDAS was investigated by adding Sr in different amounts in the hypoeutectic Al–Si alloy. No significant change in SDAS ratio was observed. % Eut/Al shown differences due to modification.
