- 論文の詳細を見る
Millimeter-sized single icosahedral quasicrystals were produced by slow cooling from melt in Zn_<80.5>Mg_<4.2>Sc_<15.3> alloy. The alloy ingots were melted at 835℃ for 1 h and then slowly cooled to an annealing temperature of 750℃ at the cooling rates of 28 K/h and 60 K/h. Scanning electron microscopy, electron back-scattered diffraction, and selected-area electron diffraction and powder X-ray diffraction experiments revealed that the single quasicrystal has a P-type (primitive-type) structure with a six-dimensional lattice parameter of 0.7110 nm, and that the structural quality of the quasicrystal is high.
