铝合金中Fe相形态的遗传性及球化机制的研究

THE HEREDITY OF IRON COMPOUND MORPHOLOGIES IN Al ALLOYS AND SPHEROIDIZING MECHANISM

试验表明，铝合金中的Fe相形态及结构存在明显的遗传性．本文提出了消除针片状Fe相遗传性、培育Fe相新晶核并使之球化的处理工艺，从而达到消除针片状Fe相危害的目的，并对Fe相球化的机理进行了研究．

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.
