Large-scale synthesis of submicron Al–Cu–Fe quasicrystals is an important direction in materials science, opening up new horizons for creating materials with unique properties. Using mechanical alloying and subsequent annealing methods, we can achieve homogeneity and a high degree of crystallinity in samples. The process of synthesizing Al-Cu-Fe quasicrystals involves the use of sintering methods and measures such as a carbon furnace or plasma spraying, which allows achieving the required characteristics (size, shape, crystal growth rate). The key point is to control the temperature regime and gas environment during the synthesis, which affects the phase composition and morphology of the resulting materials.
Quasicrystals, which differ in the degree of order and symmetry, are becoming increasingly popular due to their unusual mechanical and thermoelectric properties. Research shows that the addition of various alloying elements can significantly modify the structure and characteristics of the final material. It is also important to study the effect of annealing temperature on the processes of crystallization and the formation of stable microstructures. The research and development of new methods for large-scale synthesis of quasicrystals opens up possibilities for industrial applications, making this topic particularly important. It should be noted that further research may lead to improved mechanical properties and increased wear resistance of these materials.
Conducting such experiments not only allows us to deepen our understanding of the physical processes that occur during the formation of quasicrystals, but also opens up new prospects for the creation of highly functional materials used in various industries, from aerospace to electronics.
