Cluster-disordered glue model and role of glue atoms in the icosahedral quasicrystalline structure

Effect of Co substitution for Ni on the Ti–Zr–(Ni,Co) pseudo-ternary quasicrystal formation

“…In contrast, very limited attention is paid to the Ti-Zr-Co quasicrystal, which is disordered and forms in the composition Ti 53 Zr 27 Ni 20 by rapid quenching [6]. It is known that the average atom size and the e/a concentration are two important factors for quasicrystal formation [3,7,8]. However, a large difference in their forming ability exists for the Ti-Zr-Ni and Ti-Zr-Co quasicrystals, although Ni is very close to Co in these respects including the atom size, e/a and constructing icosahedral clusters with Ti/Zr (discussed below).…”

Stable clusters in quasicrystals: fact or fiction?

“…the matrix between the clusters), the energy balance of the flattened surface would change even better. The energy costs for moving glue atoms has been shown to be one-order of magnitude smaller than that for cluster atoms [44].…”
