Effects of the fourth component and undercooling on morphology of primary Mg-Zn-Y icosahedral quasicrystal phase under normal casting conditions [PDF]

open access: yesChina Foundry, 2009
The paper presents some results of the investigation on effects of the fourth component (Ti, C, Sb or Cu) and undercooling on the morphology, size and forming process of primary Mg-Zn-Y icosahedral quasicrystal phase (I-phase) under normal casting ...

Energy levels and their correlations in quasicrystals

open access: yes, 2006
Quasicrystals can be considered, from the point of view of their electronic properties, as being intermediate between metals and insulators. For example, experiments show that quasicrystalline alloys such as AlCuFe or AlPdMn have conductivities far ...

Phonon-phason coupling and nonlocal effects on Lamb waves in functionally graded one-dimensional hexagonal quasicrystal nanoplates

open access: yesResults in Physics
Due to the coupled phonon-phason coupling and nonlocal effects, dynamic behaviors of quasicrystal nanostructures are highly complex. Mechanics investigations have mainly focused on the statics, but rarely on dynamics, thus limiting their engineering ...

Effect of Solidification Cooling Rate on Microstructure and Mechanical Properties of an Extruded Mg-Zn-Y Alloy

open access: yesMetals, 2018
The Effect of the solidification conditions and subsequent extrusion of a Mg-3.0Zn-0.5Y (at. %) alloy containing quasicrystalline icosahedral (i-) phase was studied.

Phase behaviour of quasicrystal forming systems of core-corona particles.

open access: yesJournal of Chemical Physics, 2017
Using Monte Carlo simulations and free-energy calculations, we study the phase behaviour of a two-dimensional system of particles interacting with a hard core of diameter σHD and a repulsive square shoulder potential.

Effect of Cooling Rate on Microstructure and Mechanical Property of Mg-4.4Zn-0.3Zr-0.4Y Wrought Magnesium Alloy

open access: yesCailiao gongcheng, 2016
The Mg-4.4Zn-0.3Zr-0.4Y (mass fraction/%) alloy ingots were prepared by two casting processes namely air cooling and water cooling. These two types of Mg-4.4Zn-0.3Zr-0.4Y alloy ingots were extruded and then ageing treated under the same conditions, and ...

Conformational Asymmetry and Quasicrystal Approximants in Linear Diblock Copolymers.

open access: yesPhysical Review Letters, 2017
Small angle x-ray scattering experiments on three model low molar mass diblock copolymer systems containing minority polylactide and majority hydrocarbon blocks demonstrate that conformational asymmetry stabilizes the Frank-Kasper σ phase. Differences in
