The formation of a quasicrystalline phase in cast alloys of the Al-Cu-Fe system is one of the pressing problems in the field of materials science. Quasicrystalline phases, which differ from conventional crystal structures by their unusual symmetrical properties, attract the attention of researchers due to their uniqueness and potential applications in various fields of science and technology.

The formation of a quasicrystalline phase in cast alloys of the Al-Cu-Fe system is due to the complex interaction between atoms of aluminum, copper and iron during the crystallization of the alloy. The main attention is paid to optimizing the composition of the alloy, its heat treatment parameters and technological features of casting to form a stable quasicrystalline phase.                                                

Experimental studies are carried out using various methods for analyzing the structure and properties of materials, such as X-ray diffraction analysis, microscopy and diffusion analysis. The data obtained help to understand the mechanisms of formation of the quasicrystalline phase and determine the optimal conditions for its stable structure and properties.

Thus, studying the features of the formation of a quasicrystalline phase in cast alloys of the Al-Cu-Fe system is of great importance for the development of new materials with unique properties. Further research in this area will expand our knowledge of the structure and behavior of quasicrystalline materials, which will open up new prospects for their application in various fields of industry and science.
