| 中文摘要 | Structure types and fine structures of the stable one-dimensional (1D) quasicrystals (QCs) in an Al65Cu20Fe10Mn5 alloy have been studied using transmission electron microscopy. The ID QCs are intimately related to a prototype decagonal quasicrystal (DQC) and may be described by introducing appropriate linear phason strains into the DQC. In the present work we have observed three types of 1D QC with lattice parameters of a(1) = 8 x 0.23 nm = 1.84 nm, c(1) = 1.2 nm, a(2) = 18 x 0.23 nm = 4.14 nm, c(2) = 1.2 nm and a(3) = 13 x 0.23 nm = 2.99 nm, c(3) = 1.2 nm respectively, where c(1) = c(2) = c(3) is the period along the original tenfold axis (A10) of the prototype DQC and a(1), a(2) and a(3) are the periods along one of the A2P axes of the prototype DQC with different linear phason strains. The multiplicative values before 0.23 nm for al and a(3) belong to the numbers of one type of Fibonacci sequence with N-0 = 1 and N-1 = 1, while that for a(2) belongs to a number of another type of Fibonacci sequence with N-0 = 1 and N-1 = 3. The latter two 1D QCs are discovered for the first time. Chalk-like needle domains along the A10 direction and wavy thin plate domains perpendicular to the A10 direction have been observed in some regions of the 1D QC. |
