Registration Date 02-01-2025 Organization Institute of Impulse Processes and Technologies National Academy of Sciences of Ukraine popup.description1 Development of the scientific fundamentals of the complex electrohydraulic-electropulse disintegration of the scrap of high-density pseudoalloys of tungsten into powder microcomponents. popup.description2 The object of study is the electrodynamic, hydrodynamic, and thermodynamic processes of materials’ high-voltage electrohydraulic and contact electrospark disintegration, and chemical transformations in such systems. Research methods - physical experiment, mathematical modeling of hydrodynamic and thermodynamic processes, X-ray diffraction and sieve analysis, electron microscopy.The scientific basis for the complex electrohydraulic-electrospark disintegration of scrap from alloys W-Ni-Fe and W-Ni-Cu into powder microcomponents is developed. Electrohydraulic and electrospark processing complexation schemes have been determined, and the principles and mechanisms of electrothermal and hydrodynamic action are substantiated. The productive processing modes and ranges of their conditions’ implementation have been determined. The dependences of the granulometric composition of microcomponents on the discharge parameters are formalized. Recommendations are developed for the physical and technical implementation of the method of complex disintegration of scrap (3-5 mm) into tungsten powders or its compounds with dimensions up to 50 microns with energy consumption up to 11 kWh/kg, productivity up to 0.2 kg/h for the volume of reactor 1 dm3 with scaling. The algorithm, the controlling system for discharge modes, and the complex system for electrohydraulic and electrospark scrap processing have been developed. Results using: recycling with the production of strategic raw materials - tungsten, preparation of the batch for powder metallurgy. Product Description popup.authors Adamchuk Yurii O. Hunko Viktor I.
