Growth of a decagonal Al70Ni15Co15 single quasicrystal by the Czochralski method

Single decagonal quasicrystals of Al70Ni15Co15 were grown by the Czochralski method at Ar atmosphere. The grown crystals were of single decagonal phase 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 photography, single crystal X-ray diffraction, and high-resolution electron microscopy investigations.
