Mechanical alloying and self-propagating high-temperature synthesis (SHS) are promising methods for creating stable icosahedral quasicrystals, unique materials with complex structures and anomalous properties. Mechanical alloying is carried out using ball mills, where the powder material is subjected to intense grinding and deformation, which leads to the formation of new phases with a changed chemical and structural organization. This process allows you to control the ratio of components and obtain quasicrystals with specified properties.                                         

Self-propagating high-temperature synthesis, in turn, is used to form intermetallic compounds and complex phases from pre-mixed powders. In the SHS process, the release of heat leads to a self-propagating reaction, which is the basis for the rapid formation of a quasicrystalline structure. Thus, the combination of mechanical alloying and SHS opens new horizons in the research and production of quasicrystals. These materials find applications in various fields including tribology, catalytic processes and electronics due to their unique combination of mechanical and thermal properties.
