快速冷凝Al＿（47）Cu＿（25）Fe＿8Mg＿（20）合金粉末的TEM研究

A TEM Study on Rapidly Solidified Al_(47)Cu_(25)Fe_8Mg_(20) Alloy Powders

本文用透射电子显微镜研究了快速冷凝Ａｌ＿（４７）Ｃｕ＿（２５）Ｆｅ＿８Ｍｇ＿（２０）合金粉末。在淬火态粉末中，发现并确定了四个晶体相，在８００℃热处理的粉末中，观察到了Ｆ型二十面体准晶相。

The rapidly solidified Al_(47)Cu_(25)Fe_8Mg_(20) alloy powders have been studied by transmissionelectron microscopy (TFM). In the as-quenched powders, four crystalline phases have been found anddetermined by double tilting method in TFM. In the 800℃ heat-treated powders, the F-type icosahedralquasicrystal phase has been observed.
