利用SEM、EDX和XRD等方法
分析了铸造Al-25Si-xFe-yMn合金的凝固组织
其中
Mn与Fe之比(y/x)在0~1之间。结果表明
Mn能显著改善Al-25Si-xFe-yMn合金的凝固组织
在凝固过程中能生成α-Al15(Fe
Mn)3Si2相
而取代针状δ-Al4FeSi2和β-Al5FeSi相。另外
随着y/x比值的提高
α-Al15(Fe
Mn)3Si2相的含量不断增多
而针状相的含量却减少
当y/x比值增加到1时
只存在α-Al15(Fe
Mn)3Si2相。
Solidification structure of cast AL-25Si-xFe-yMn alloy was observed by SEM (scanning electron microscope)
EDX and XRD
where Mn/Fe in weight ratio is in range of 0
1
. The results show that Mn can greatly refine microstructure of the alloy as a result of creation of α-Al15(Fe
Mn)3Si2 phase substituting for acicular δ-Al4FeSi2 and β-Al3FeSi phase. In addition
with increasing in Fe/Mn weight ratio
Mn)3Si2 phase is increased and acicular phase is decreased. When Fe/Mn weight ratio is 1
Mn)3Si2 phase is observed in the alloy only.
