Essay

It was studied how molten metal flow affected the formation macrostructures of Al-Si hypereutectic alloys chill castings. The effect of heat treatment of molten Al-21%Si alloy on the formation of eutectic structure has been investigated. The regularities of structural constituents morphology formation under crystallization in molten metal flow have been ascertained. It was shown that stressed state of the phases in Al-Si alloys promote the formation of the metastable intermediate phase during the heating. The aluminum side of experimental phase transition diagram was constructed.
