The majority of aluminum die casting alloys are based on the Al–Si system, as silicon dramatically improves fluidity, hot tear resistance, and the feeding of shrinkage porosity for aluminum castings. Most of these Al–Si alloys are hypoeutectic or eutectic compositions, containing between 7.5% and...

The existence of minor shrinkage porosity is evident in the samples, that does not otherwise influence outcome of the present study and is easily addressed in industrial scale. It is worth noting that the angular dark-colored particles appear to form in dendritic morphology in some cases (Figure...
