“…It should be noted that in contrast to Al-Cu-Fe systems, where an icosahedral QC phase is formed, Al-Cu-Cr systems more often form decagonal QC phases; however, as it was shown in [ 18 ], the decagonal QC of Al-Ni-Co systems shows excellent behavior as a filler for polymer matrices, and we can expect the same behavior from Al-Cu-Cr decagonal QC. Recently we investigated the formation of decagonal Al-Cu-Cr QC powder by mechanical alloying with subsequent annealing [ 25 , 39 ]. In the present study the synthesized powders were applied as hard fillers to improve the wear resistance of antifriction FEP-based composites.…”

Antifriction hybrid fluorinated ethylene propylene-based composites filled with quasicrystalline Al73Cu11Cr16 powder, polytetrafluoroethylene, synthetic graphite and carbon black were elaborated and investigated. Composite samples were formed by high-energy ball milling of initial powders mixture with subsequent consolidation by injection molding. Thermal, mechanical, and tribological properties of the obtained composites were studied. It was found that composite containing 5 wt.% of Al73Cu11Cr16 quasicrystals and 2 wt.% of nanosized polytetrafluoroethylene has 50 times better wear resistance and a 1.5 times lower coefficient of dry friction comparing with unfilled fluorinated ethylene propylene. Addition of 15 wt.% of synthetic graphite to the above mentioned composition allows to achieve an increase in thermal conductivity in 2.5 times comparing with unfilled fluorinated ethylene propylene, at that this composite kept excellent tribological properties.

“…Several applications, other than protective coatings and highstrength alloys, have also been studied for quasicrystals, including their use as: solar light absorbers [45], abrasive polishing agent [54], reinforcing agents in polymers [55,56], catalysts [57,58,59], hydrogen storage [60,61,62,63], among others. We will not discuss them in this review any further.…”

Quasicrystalline alloys and their composites have been extensively studied due to their complex atomic structures, mechanical properties, and their unique tribological and thermal behaviors. However, technological applications of these materials have not yet come of age and still require additional developments. In this review, we discuss the recent advances that have been made in the last years toward optimizing fabrication processes and properties of Al‐matrix composites reinforced with quasicrystals. We discuss in detail the high‐strength rapid‐solidified nanoquasicrystalline composites, the challenges involved in their manufacturing processes and their properties. We also bring the latest findings on the fabrication of Al‐matrix composites reinforced with quasicrystals by powder metallurgy and by conventional metallurgical processes. We show that substantial developments were made over the last decade and discuss possible future studies that may result from these recent findings.
