Abstract

Scandium addition in Al–Si alloys can reduce grain size and modify the structure from flake-like to fibrous. To use this Sc-modified Al–Si alloy in practical applications, there are many factors that need to be studied, including porosity formation. However, there is limited available information with regard to the effect of Sc on porosity formation. This research used the Tatur test mold to investigate the effect of strontium and scandium on porosity formation in Al–6Si–0.3 Mg alloys. Sc addition promoted the fibrous structure of eutectic silicon and reduced grain size. Sc addition also resulted in smaller and more dispersed porosity across the samples compared to that of unmodified samples. Once the Sc addition reached 0.4 wt%, the τ phase (AlSi2Sc2) was clearly observed. It is believed that the τ phase promoted more oxidation during casting and eventually led to higher numbers of porosity in the casting.
