When Al-Si alloys contaminated with Fe were superheated above 800°C and cast, Chinese scripts of an AlFeSi compound crystallized instead of needle-like compounds T2 or β-AlFeSi. In oder to clarify this phenomenon, effects of superheating temperature, thermal histry of the melt after superheating and solidification time on the crystallized structure of AlFeSi compounds and crystallizing prosess were examined. Chinese scripts of AlFeSi compounds crystallize in the Fe-enriched residual liquid through nonequilibrium solidification and are insusceptible to thermal history of the melt after superheating. Minor impurities have significant effects on the crystallized structure of AlFeSi compounds.
