Abstract
Al -Si alloys are one of the most widespread engineering casting materials with eutectic structure. In Al-Si alloys eutectic has a skeleton-like structure [1], which forms as a result of the coupled growth of Al and Si based solid solutions crystals. The silicon solid solution initiates formation and leads the coupled growth of the eutectic grain [2]. Eutectic branching affects ductility of Al-Si alloys. In general, the ability of crystal to grow in the branched form depends on type of chemical bond in the solid, cooling rate and content of impurities in the liquid and solid phases [2].
