Dislocations in icosahedral quasicrystals [PDF]

Chemical Society Reviews, 2012
Dislocations in quasicrystals, as a direct result of the lack of translational symmetry in these materials, possess various salient features. The Burgers vector of a dislocation in an icosahedral quasicrystal is a 6-dimensional vector, which reflects the fact that the dislocation, besides the phonon-type strain field analogous to dislocations in ...

Quasicrystals

Journal of Non-Crystalline Solids, 1985
We introduce the concept of quasicrystals and discuss their diffraction patterns. The idea of local isomorphism is argued to be a physically meaningful one.

Electronic structure of quasicrystals [PDF]

, 2005
Quasicrystals are aperiodically ordered solids. Their unusual transport properties, especially the low electric conductivity, are indications of the particular electronic structure of these materials. There are several approaches toward understanding the

On Elastic Stability and Positive Definiteness for One-Dimensional Quasicrystals

Crystals
In this work, a proper formulation of the elastic stability and positive definiteness of the elastic energy density of one-dimensional quasicrystals is provided. Based on an appropriate Voigt notation, the Sylvester criterion is applied and the necessary

Bridging the local configurations and crystalline counterparts of bulk metallic glass by nanocalorimetry

Journal of Materials Research and Technology, 2019
The structural understanding of crystallization in bulk metallic glasses (BMGs) has attracted much attention while rapid crystallization occurring under controllable conditions is less involved.

Quo Vadis Quasicrystals?

Crystals, 2017
This Special Issue aims at gaining a deeper understanding on the relationship between the underlying structural order and the resulting physical properties in aperiodic systems, including quasicrystalline and related complex metallic alloys, photonic ...

Shock Synthesis of Five-component Icosahedral Quasicrystals [PDF]

, 2017
Five-component icosahedral quasicrystals with compositions in the range Al_(68–73)Fe_(11–16)Cu_(10–12)Cr_(1–4)Ni_(1–2) were recently recovered after shocking metallic CuAl_5 and (Mg_(0.75)Fe_(0.25))_2SiO_4 olivine in a stainless steel 304 chamber ...

Laser induced desorption and ablation: mechanism of metal removal from an Al-Cu-Fe alloy and a quasicrystal of the same composition

International Journal of Photoenergy, 2001
Quasicrystals are a special class of metallic alloys that share some of the properties of crystals. Their structures reduce to a single repeating unit like that of the unit cell of a crystal.
