摘要
在快速凝固Ａｌ－Ｆｅ－Ｖ－Ｓｉ合金棒材中发现了１种圆形准晶相，尺寸为０２～０５μｍ，成分为Ａｌ－８０ａｔ％Ｆｅ－２．１ａｔ％Ｖ－３．２ａｔ％Ｓｉ。对此准晶进行了透射电镜、Ｘ－光衍射结构分析，并对准晶的形成机制进行了讨论。
A spheroidal quasicrystalline phase with the grain size of 0.2～0.5μm and the chemical composition of Al-8.0at.%Fe-2.1at.%V-3.2at.%Si has been observed in the RS Al-Fe-V-Si extrusions.TEM and XRD analyses were carried out to investigate the structural features of this phase.The mechanism of the phase formation has been discussed.
