Thermal Processes Under Mechanical Treatment of F'owders and their Role in their Structure and Properties Formation of Dispersed Systems

摘要

The defect formation as well as thermal processes that occur in materials under mechanical treatment are of special interest for the specialists working with disperse media. So, after switching on the grinder, grinding - defeat formation process is accompanied with heat release. In other words, the mechanical reactor becomes to work simultaneously as a heat reactor. The heat released is being spent for heating DM, grinder components and environment. This report deals with some possibilities of experimental EPR study of the role of annealing that the spiking and accumulating mechanothermal effects play ir the formation of a defect structure of the powders under mechanical treatment (grinding, pressing). The interesting possibilities of the directed modification of powders defect structure by changing the mechanical treatment conditions are discussed.
