Abstract
The single crystal growth of decagonal quasicrystals in the Al–Co–Ni system has been investigated using the Czochralski method. Using a ceramic tip instead of a native seed, single-grain quasicrystals of average composition Al 71Co 18Ni 11 and approximately 1 cm 3 in size have been grown. Very low pulling rates (0.25–0.5 mm/h) were used. Axial segregation and structural perfection were investigated by electron-probe microanalysis and neutron diffraction. The liquidus temperature of the starting melt and composition of the decagonal phase agree well with the published phase diagram data.
