摘要：
A new crystalline phase (called 'W-(AlNiCo) phase'), which is closely related to Al-Ni-Co decagonal quasicrystals with 0.4 nm and 0.8 nm periodicity, has been found in an Al72.5Ni7.5Co20 alloy annealed at 950 degreesC. The W-(AlNiCo) phase has a monoclinic structure with lattice parameters a=3.99 nm, b=0.82 nm, c=2.36 nm and beta =90 degrees, and the space group of Cm (No. 8). Structural characteristics of the W-(AlNiCo) phase and the resemblance to those of an Al-Ni-Co pentagonal quasicrystal are discussed from atom-scale observations using high-angle annular detector dark-held scanning transmission electron microscopy and high-resolution electron transmission microscopy.
