Icosahedral quasicrystals of aluminum, copper and iron are unique structures with unusual properties. The surface of these metals has a complex microstructure that can be altered by scratches and deformations. Scratches on the surface can cause local deformation and change the distribution of atoms, which in turn affects the mechanical and thermal properties of quasicrystals.

Studying the microstructures of the surface of icosahedral quasicrystals after deformation and scratches allows us to understand the mechanisms of their formation and the effect on the properties of the material. For example, scratches can lead to the formation of new phases or increased strain around defects, which can affect the strength and stability of quasicrystals. In addition, changes in surface microstructure can also affect the electrical and thermal properties of the material.                                                  

Studies of the surface microstructures of icosahedral quasicrystals of aluminum, copper and iron are of great importance for the development of new materials with unique properties. Understanding the effect of scratches and deformations on the microstructure will allow the creation of materials with improved strength, thermal conductivity and other characteristics. In addition, studying the behavior of icosahedral quasicrystals after exposure to external factors will help optimize their use in various industries.

Further studies of the surface microstructures of al-cu-fe icosahedral quasicrystals will help deepen our understanding of their properties and potential applications. Analyzing the effect of scratches and deformations on the surface will help develop new methods for improving the mechanical and physical properties of the material. Thus, studying surface microstructures is a key aspect in understanding the properties and behavior of icosahedral quasicrystals and their possible applications in various fields.
