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...
This work studies the dry friction properties of sintered Al 62.5 Cu 25 Fe 12.5 samples with quasicrystalline as well as the B2 (CsCl) type structures. Friction experiments were carried out on a pin-on-disc-type tribometer. The structure of the specimens was measured by means of X-ray diffraction. Chemical compositions were obtained by means...
