摘要

Obtaining new materials using classical technologies brings tothe forefront the development of tribophysical and tribochemical methods used for powder production. All the more, as mechanical activation can transform the starting components into a metastable (amorphous) state. This can even lead to mechancchemical synthesis. In an open system, which is not in equilibrium, such as a system in which a tribophysical process occurs, kinetic phase transformations are possible. They are accompanied by processes of internal structural self-organization. Changes of dissipative structures can also be caused by the occurrence of fluctuations for critical values of system parameters, or by changes of external parameters, that lead to the disappearance of the starting stable state and dynamical reorganization of dissipative structures.
