摘要：

Correlated domains without strict periodicity but with only a periodic substructure (a, b = 5.18 nm, c = 0.82 nm, gamma = 108degrees) were observed in the system Al-Ni-Co by high-resolution transmission microscopy and electron diffraction. A periodic substructure is sufficient to produce a diffraction pattern corresponding to a nanodomain structure of a twinned approximant.
