Information × Registration Number 0211U009599, 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 30-12-2011 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: determination of physical mechanisms conditioning an accelerated densification, sintering and superplasticity of nanocrystalline powder materials 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.
