- X-ray diffraction analysis, scanning and transmission electron microscopy, thermal analysis and measurement of chemical composition were implemented to determine structure, thermal stability and chemical composition of the decagonal quasicrystal in $Al_{73}Cu_{11}Cr_{16}$ alloy produced by long-term mechanical alloying of elemental powders followed by annealing at 700°C. According to the TEM investigation such a technique permits to produce a single-phase nanostructural quasicrystal with grain size about 60 nm. Differential thermal analysis revealed that the decagonal phase does not exist above 923°C and undergoes incongruent two-stage melting coming to the end at 1100°C.
