Special Issue "Structure and Properties of Quasicrystalline Materials"
Deadline for manuscript submissions: 31 March 2018
Dr. Dmitry A. Shulyatev
Since 1984, when Shechtman and coworkers published their pioneering paper on non-crystallographic rotational symmetry in rapidly quenched Al6Mn alloy, there has been an extraordinary interest in investigations of the structure and properties of this new type of atomic order in the solid state, termed “quasicrystals”. Quasicrystals have aperiodic long-range atomic order and symmetry, forbidden for periodic systems. They demonstrate unusual physical properties: Being alloys of “good” metals, they exhibit a large electrical resistance with a negative temperature coefficient, low thermal conductivity, very high hardness, low surface energy, low coefficient of friction, high catalytic activity, and a great deal of other interesting properties.
A massive amount of experimental and theoretical data on the structure and physical properties of quasicrystals has been accumulated over the more than 30 years of their investigation. This Special Issue will focus on the most recent advances in the field of quasicrystals and their crystalline approximants.
The possible topics include, but are not limited to:
- Structure and Mathematical Modeling of Quasicrystals and Approximants
- Soft Matter Quasicrystals
- Formation and Stability of Quasicrystals
- Phason Dynamics
- Electron Microscopy and Surface Investigations of Quasicrystals and Approximants
- Electronic Structure and Transport in Quasicrystals and Approximants
- Magnetic, Thermal and Mechanical Properties of Quasicrystals and Approximants
- New Quasicrystalline alloys

Title: Formation of quasicrystalline phases and their close approximants in cast Al-Mn base alloys modified by transition metals

Abstract: The aim of presented research was to study the influence of Cr, Co, Ni and Cu addition on the formation of quasicrystalline particles in 94Al-6Mn base alloy during casting at intermediate cooling rates. Based on the obtained results, Cu and Ni enhance quasicrystalline phase nucleation compared to the unmodified binary composition. In the case of Cu addition formation of quasicrystalline phase takes place along whole thickness of the prepared casting but its fraction and morphology depends on the cooling rates present in the different parts of the sample. Based on our previous works on the beneficial effect of Fe addition a quaternary alloy, containing both Fe and Cu, was prepared to evaluate the effect of the simultaneous presence of these elements on the microstructure of obtained castings.
