论文摘要

已经进行了扫描电子显微镜(SEM)和透射电子显微镜(TEM)研究,对烧结的Al-Cu-fe二十面式准晶体(IQC)进行了研究,以了解以前在标准互动scratch测试中产生的轨道中注意到的某些延展性的起源。显示了二十面体相对调制结构的转化,并在轨道下面发现了IQC向BCC相的转化。还观察到双胞胎和错位。

Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) investigations of sintered Al-Cu-Fe icosahedral quasicrystal (IQC) have been carried out to understand the origin of some ductility previously noticed within tracks produced by standard tribological scratch tests. Transformation of the icosahedral phase to a modulated structure is shown and a transformation of the IQC to a bcc phase has been found beneath the tracks. Twins and dislocations have also been observed.
