In recent years, the development of quasicrystalline alloys has attracted the attention of scientists and engineers due to their unique tribological characteristics, which significantly exceed the properties of traditional metallic materials. The main focus of this study is the influence of microstructure on the mechanical properties of these alloys and their interaction under contact conditions.
Quasicrystals, with complex symmetry and low symmetry, exhibit unique properties such as high hardness, low friction coefficient and excellent wear resistance. Formulation of optimal alloying additives and control of heat treatment processes play a key role in achieving the desired microstructure.
In addition, special attention is paid to the use of modern diagnostic methods, such as electron microscopy and x-ray diffraction, which makes it possible to more accurately study and control the formation of the quasicrystalline phase. As a result, the resulting alloys not only have improved performance properties, but can also be adapted for various operating conditions, which opens up new horizons for their use in highly loaded structures and tribological systems.
