Eutecticum Morphology in Al-Si Alloys

Abstract:

The structure of casting silumins (Al-Si alloys) contains a big share of eutecticum (40-75%) which, as mentioned afore, enhance fluidity and decrease tendency towards formation of clefts and microporosity. Due to this fact the properties of α - phase on one hand as well as quantity, morphology, size, and distribution of eutectic silicium on the other hand are the most significant factors influencing mechanical properties of the casting.
