Recent studies show typically brittle quasicrystals can exhibit remarkable ductility of over 50% strains at room temperature and sub-micrometer scales (<500 nm). [62] An application was the use of low-friction Al–Cu–Fe–Cr quasicrystals [63] as a coating for frying pans.
Complex metallic alloys is an umbrella term for intermetallic compounds with a relatively large unit cell.There is no precise definition of how large the unit cell of a complex metallic alloy has to be, but the broadest definition includes Zintl phases, skutterudites, and Heusler compounds on the most simple end, and quasicrystals on the more complex end.
The book is divided into two parts. The first part covers the history of crystallography, the use of X-ray diffraction to study crystal structures through the Bragg peaks formed on their diffraction patterns, and the discovery in the early 1980s of quasicrystals, materials that form Bragg peaks in patterns with five-way symmetry, impossible for a repeating crystal structure.

These form quasicrystals in the stoichiometry around R 9 Mg 34 Zn 57. [2] Magnetically, they form a spin glass at cryogenic temperatures. While the experimental discovery of quasicrystals dates back to the 1980s, the relatively large, single grain nature of some Ho–Mg–Zn quasicrystals has made them a popular way to illustrate the concept ...

The term hyperuniformity (also independently called super-homogeneity in the context of cosmology [22]) was coined and studied by Salvatore Torquato and Frank Stillinger in a 2003 paper, [1] in which they showed that, among other things, hyperuniformity provides a unified framework to classify and structurally characterize crystals, quasicrystals, and exotic disordered varieties.
