“…AlMn alloys produced by melt spinning show five-fold rotational symmetry that is incompatible with the transitional symmetry of crystals. Reflectance from 300 nm to 20 µm is about 0.6 and is nearly independent of wavelength for all stable ordered icosahedral quasicrystals [175]. Quasicrystals exhibit high thermal and chemical stability.…”

“…Thermodynamically stable quasicrystal-forming alloys (i.e., AlCuFe, AlCuRu, and AlMnPd films) can be used as selective absorbers. "Materials with an icosahedral point group or other crystals of forbidden rotational symmetries are referred to as 'quasicrystals'" [175]. AlMn alloys produced by melt spinning show five-fold rotational symmetry that is incompatible with the transitional symmetry of crystals.…”

“…Furthermore, crystallization of amorphous alloys may also evolve quasicrystalline phases, as in the case of Pd 60 U 20 Si 20 ͑Ref. Quasicrystals have some particular properties, e.g., interesting electrical and thermal transport properties, 14,15 high photon absorption, 16 high hardness, high corrosion resistance, and low coefficient of friction. 10 Recently, quasicrystals were also obtained by crystallization of Zr 65 Cu 17.5 Al 7.5 Ni 10 ͑Refs.…”

The Zr57Cu20Al10Ni8Ti5 alloy solidifies into an amorphous phase upon rapid quenching or casting at low cooling rates. However, the amorphous alloys formed at different cooling rates exhibit different crystallization behavior. The slowly cooled bulk amorphous alloys prepared by copper mold casting reveal a first crystallization peak at 715 K upon heating at 0.33 K/s and crystallize via precipitation of an icosahedral quasicrystalline phase in the first crystallization step. The rapidly quenched ribbons exhibit a first crystallization peak at 720 K and crystallize by simultaneous precipitation of the quasicrystalline phase together with Zr2Cu and Zr2Ni intermetallic phases in the first stage of crystallization. It is supposed that the undercooled Zr57Cu20Al10Ni8Ti5 melt has a tendency to develop an icosahedral short-range order, which is favored by low cooling rate. As a result, the bulk amorphous alloy has a short-range order close to a quasicrystalline phase. In contrast, the structure of the ribbon is more similar to that of the melt at high temperature and the atoms are oriented more randomly.

Shift and broadening of surface polaritons of sapphire upon deposition of a quasicrystalline film

et al. 2012

The influence of a quasicrystalline Al-Pd-Re film on the shift and broadening of surface polari tons of a substrate (sapphire) has been studied. Measurements have been performed both on a sample con taining only the quasicrystalline phase and on a sample which, in addition to the quasicrystalline phase, con tains the crystalline (metallic) phase. The complex dielectric function of the films in the mid IR region (650⎯800 cm -1 ) has been estimated.
