Information × Registration Number 0213U004160, 0111U000887 , R & D reports Title Determination of effective mechanisms of consolidation of nanocrystalline powder materials at hot pressing with heating by pulsed electric current. popup.stage_title Head Laptev Alexander M., Registration Date 22-02-2013 Organization Donbass State Engineering Academy popup.description2 Object of research: the new process of hot pressing of nanocrystalline powder materials with heating by pulsed electric current. The goal of investigation: definition of current role and behavior of pulsed electric current, applied pressure, particle size of nanocrystalline powders and state of their surfaces on the kinetics of consolidation at hot pressing with heating by a pulsed electric current. The methods of research: theoretical analysis by finite element method, experimental investigations on equipment for hot pressing with heating by electrical current. Theoretical and practical results: a theory of acting mechanisms and recommendations on improvement of technology of hot pressing of powder materials with heating by a pulsed electric current. Novelty: new knowledge concerning mechanisms which influence deformation of nanocrystalline powder materials at heating by a pulsed electric current. Efficiency of implementation: obtained knowledge makes possible an optimization of a process of hot pressing of powder materials by retaining both initial nanocrystalline structure and unique properties. Area of application: materials working by pressure, ceramics production, powder metallurgy, research and development in the field of natural and engineering sciences.
