Ulianov Chuvash State University, 15 Moskovsky Prospekt, Cheboksary, 428015, Russian Federation Abstract The paper presents the results of using the method of reactionary mechanical alloying in attritors in the preparation and further industrial production of bulk nanostructured materials based on metal powders with high strength properties at elevated temperatures and good wear resistance. The features of the structure and its influence on the properties of these materials are described. Information on the production of these materials and high-resource products from them for various fields of technology is provided. Keywords reactionary mechanical alloying, attritor, mechanochemical synthesis, powder metallurgy, compaction, extrusion, recrystallization temperature, wear resistance.
