Investigation of an icosahedral AlCuFe quasicrystal at high pressures Quasicrystals, long-range order materials without translational symmetry, are a unique class of solids whose properties occupy an intermediate position between crystalline and amorphous substances. The discovery of the icosahedral phase of AlMn in 1984 by Dan Shechtman revolutionized traditional ideas about solid-state physics and materials science. […]
Investigation of viscosity and supercooling of Al-Cu-Fe melts This paper presents the results of a comprehensive study of the viscosity and supercooling propensity of Al-Cu-Fe melts in the vicinity of compositions corresponding to the formation of the icosahedral phase. Viscosity measurements were carried out by the torsional oscillation method over a wide temperature range covering […]
Investigation of dynamic properties of icosahedral quasicrystals Icosahedral quasicrystals (i-phases) are exotic materials that occupy an intermediate position between periodic crystals and amorphous structures. Their unique properties, such as forbidden axes of high-order symmetry (for example, five-fold symmetry), order at large distances without translational periodicity, and unusual electronic structure, are of great interest from both […]
Prospects for high-entropy eutectic alloys in materials science Materials science is relentlessly striving to create alloys with unique properties that are superior to traditional materials. High-entropy alloys (HES), which are multicomponent systems consisting of five or more elements in equal or close to equal atomic concentrations, occupy a special place in this innovation race. Unlike […]
Investigation of corrosion resistance of Al–Cr and Al–Cr coatings– The introduction of modifying elements such as chromium and nitrogen into aluminum coatings applied by magnetron sputtering opens up prospects for a significant improvement in their corrosion resistance. The amorphous structures obtained as a result of the sputtering process contribute to the formation of a uniform […]
New opportunities for quasicrystalline Al-Cu-Fe foams in materials Al-Cu-Fe quasicrystalline foams represent a new class of materials with a unique combination of lightness, high porosity, and potentially excellent mechanical properties. These foams, consisting of a metal matrix based on aluminum, copper and iron with a quasi-crystalline structure, attract considerable attention of researchers due to the […]
Comparative analysis of the mechanical properties of quasicrystals and crystals In this paper, a comparative analysis of the mechanical properties of the quasicrystalline and nearby crystalline phases in the Al–Cu–Fe system is performed. Microhardness, brittleness, and deformation behavior of materials are considered. The analogy in the mechanical response between these structurally different phases is emphasized, […]
Investigation of fast-hardening aluminum alloys: results and conclusions In recent decades, fast-hardening aluminum-based alloys (BTS) have attracted considerable attention due to their potential in various fields of technology. Rapid solidification of the melt makes it possible to obtain a microcrystalline or amorphous structure, which leads to improved mechanical properties compared to traditional alloys. Alloying with […]
