摘要： Al$_{65}$Cu$_{20}$Fe$_{15}$ bulk is synthesized with the high-pressure synthesis (HPS) method. Various analytical techniques, such as single crystal x-ray diffraction (SXRD), scanning electron microscopy equipped with energy-dispersive x-ray spectroscopy, and transmission electron microscopy, are employed to characterize the sintered bulk and confirmed its quasicrystalline structure. The electrical resistivity of the HPS quasicrystal specimen is measured from 2 K to 300 K, revealing a significantly elevated value in comparison to samples prepared via alternative methods. Nanoindentation testing demonstrates exceptional hardness and elastic modulus of our Al$_{65}$Cu$_{20}$Fe$_{15}$ quasicrystal, consistent with existing results. The ratio of hardness to elastic modulus further highlight the potential superior wear resistance of the Al$_{65}$Cu$_{20}$Fe$_{15}$ quasicrystal. Differential scanning calorimetry measurement conducted on the HPS Al$_{65}$Cu$_{20}$Fe$_{15}$ quasicrystals reveal a high melting point of 877 $^\circ$C.
