摘要: 研究了Mg元素对铸造Al-10%Fe过共晶合金初生Al3Fe相形态的影响。研究发现,加入Mg对初生Al3Fe相生长产生影响,由原来的发达针状向树枝状→小针(片)状、不规则块状转变。对Mg元素的影响机理做了分析。

关键词: Mg 铸造Al-10%Fe合金 初生Al3Fe相

Abstract: The effect of Mg on the morphology of primary Al3Fe phase in hypereutectic Al-10%Fe casting alloy is investigated. It is shown that the morphology of primary Al3Fe phase is changed from coarse needle-like to branch-like, finally to fine needle(plate)-like or irregular chunk-like with addition of Mg element.

Key words: Al-10%Fe casting alloy, Al3Fe phase, Mg, Primary
