摘要：

Single quasicrystals Al(72)Ni(12)Co(16) and Al(72)Pd(19)Mn(9) alloys have been grown by the floating-zone method and Zn(46)Mg(51)Ho(3) alloy by the Bridgman method. In these three systems, single quasicrystals with dimensions of the order of a centimeter have been successfully grown. X-ray diffraction and neutron diffraction show that these single quasicrystals are as good as the best crystals. We therefore assert that quasicrystals are a metallic bulk matter with a degree of order equal to that of best crystals. By quenching the liquid, we observed flat solid-liquid interface perpendicular to the growth directions in Al-Ni-Co and AI-Pd-Mn alloys. (C) 1999 Published by Elsevier Science B.V.
