Vacancy ordered phases in Al-Cu-Ni as quasiperiodic superlattice approximants
Source abstract
Abstract
Vacancy ordered phases in the Al-Cu-Ni system have an arrangement of vacant and filled sites in the truncated Fibonacci sequence along the [111] direction. The length scales involved are commensurate and in the limit a quasiperiodic superlattice is obtained. The implication of having commensurate length scales and quasiperiodicity in conjunction is studied using the concept of average lattices and projection formalism.
