Object of research: new process of electropulse consolidation of powder materials with nanocrystalline structure, which occurs during short-term impact acting high power electric current and mechanical loading. The aim of investigation: definition of the fundamental mechanisms for powders consolidation, which are loaded by mechanical pressure in powerful electromagnetic field during flowing through them current pulse with high power. The methods of research: thermodynamic analysis of the powder composition components interaction, mathematical modeling of the spatiotemporal temperature field of powder material. Theoretical and practical results: results of calculation of apportionment of temperature field in the bulk of the powder composition under electropulse consolidation. Novelty: classification of physical phenomena and mechanisms operating during the current high power pulse through the powder material, loaded by mechanical pressure, the theory of electropulse consolidation, which will take into account entire combination of these mechanisms and phenomena. Efficiency of implementation: obtained knowledge allows to formulate a new theory of electropulse consolidation of powder materials and create a method for determining the optimum process parameters that provide full consolidation of powders with their original nanocrystalline structure. Area of application: materials working by pressure, ceramics production, powder metallurgy, research and development in the field of natural and engineering sciences.
