Abstract The morphologies and structures of iron compounds in an al-Si alloy have remarkable heredity. a technique has been presented for eliminating the heredity of needle-form iron compounds and planting nuclei for new iron compounds and spheroidizing them, and then the harmful effect of needle-form iron compounds in al-Si alloy on the mechanical property can be eliminated. The spheroidisation mechanism of iron compounds has also been investigated.
