چکیده

We review the stability of various icosahedral quasicrystals (iQc) from a metallurgical viewpoint. The stability of stable iQcs is well interpreted in terms of Hume-Rothery rules, i.e. atomic size factor and valence electron concentration, e/a. For metastable iQcs, we discuss the role of phason disorder introduced by rapid solidification, in structural stability and its interplay with chemical order and composition.

Absence of fine structure in the photoemission spectrum of the icosahedral Al-Pd-Mn quasicrystal

The results of the low-temperature ultrahigh-energy-resolution photoemission studies of a single-grain icosahedral alloy Al70Pd21.5Mn8.5 have been presented. The existence of the theoretically predicted pseudogap in the density of states at the Fermi energy has been confirmed. No evidence of the theoretically predicted spikiness of the density of states could be observed. It has been suggested ...

Local Order in Single Grain Cd-Yb Icosahedral Phase

Single grains of icosahedral Cd84Yb16 quasicrystalline phase were characterized using high resolution transmission electron microcopy (HRTEM) technique. Image reconstruction of the obtained multiple through-focal series for both the two and five-fold axes are consistent with the local cluster structure of concentric polyhedra consisting of Cd tetrahedron (1/3 occupied icosahedron), Cd dodecahed...

Atom Clusters with Icosahedral Symmetry in Cubic Alloy Phases Related to Icosahedral Quasicrystals

Icosahedral symmetry can not be allowed to exist in crystalline phases. However, the structures of some crystalline alloy phases are characterized by packing of atom clusters with icosahedral symmetry, and their structures are considered to be closely related to the structures of icosahedral quasicrystals. For examples, a cubic α-(AlMnSi) crystalline phase with a lattice constant of 1.264 nm is...

Ideal AlMnSi quasicrystal : a structural model with icosahedral clusters

A model for Al(Si)Mn quasicrystals is proposed. It is characterized by pure quasiperiodic long range order with icosahedral symmetry. The density and concentrations fit to the experimental values. The interatomic distances are compatible with crystallographic data and compare well to the related 03B1 phase. A large number of icosahedral clusters (Mackay icosahedra) are present in the model. J. ...

Metallic–covalent bonding conversion and thermoelectric properties of Al-based icosahedral quasicrystals and approximants

In this article, we review the characteristic features of icosahedral cluster solids, metallic-covalent bonding conversion (MCBC), and the thermoelectric properties of Al-based icosahedral quasicrystals and approximants. MCBC is clearly distinguishable from and closely related to the well-known metal-insulator transition. This unique bonding conversion has been experimentally verified in 1/1-Al...
