Thermal analysis during solidification of cast Al–Si alloys

摘要: Abstract Solidification of a series aluminium alloys was studied by means thermal analysis; the study centred on effect that silicon and iron exert temperatures for onset different microstructural characteristics. The were prepared in gas fired furnace poured into graphite moulds instrumented with type K thermocouple. cooling curve registered aid computer-driven data logging system derived to determine formation pre-eutectic dendrites, those Al–Si eutectic complex Al–Si–Cu–Mg eutectic. It found exerts strong influence two former temperatures, whereas third one is independent content or iron.
