Growth of a decagonal Al70Ni15Co15 single quasicrystal by the Czochralski method

Single decagonal quasicrystals of Al70Ni15Co15 were grown by the Czochralsk i method at Ar atmosphere. The grown crystals were of single decagonal phas e without any secondary phases due to the peritectic reaction and contained a large single quasicrystal of cm order size. The high quality and single quasicrystallinity of them were examined by the Laue transmission photograp hy, single crystal X-ray diffraction, and high-resolution electron microsco py investigations.
