The paper is dedicated to solving the scientific problem of increasing the efficiency of the shock-wave process of scrap of hard alloys with their subsequent restoration on the basis of the choice of the scheme of detonation of a bristle ex-plosive substance, justification of its regime and structural parameters, establishing dependencies of the interaction with the crushed mass and improving the technology of cutting, destroying and forming tool of tungsten cobalt and tung-sten-nickel alloys with significant cost savings of strategic raw materials direct recovery of recyclable materials without the use of thermochemical and metallurgical methods. The paper considers and analyzes the influence of shock-wave processing of scrap of hard alloys with their subsequent restoration without using thermo-chemical and metallurgical methods as well as saving tungsten and cobalt as strategic materials. The obtained analytical correlations and the results of numerical integration allowed to determine the connection between the parameters of initiation of planar and cylindrical surfaces and to establish the nonlinearity of the interrelation of parameters at the initiation of explosion of plane and cylindrical surfaces un-der other equal conditions. The mathematical model of calculation of geometrical parameters of cylindrical and flat pressure treatment devices is developed, taking into account the created calculation model of a porous medium consisting of a mixture of two or more materials. It is shown that the effect of loading on the reactivity of powders significantly increases the internal energy, which greatly accelerates the processes of compacting and sintering of powders, while the chemical activity increases. Detected phenomena of allotropic transformations in the mechanical shredding of scrap of solid alloys with the energy of explosion of brisant explosives, which made it possible to make solid alloys with increased physical and mechanical characteristics. The technology of grinding of solid alloy crushed grains has developed further, which differs by introducing the method of improving the efficiency of grinding of crushed grains of hard alloy due to the establishment of the criteria of its granularity, which has reduced the time of the grinding process. The industrial highly effective technology of production of cutting, destroying and shaping tools from tungsten-cobalt and tungsten-nickel alloys is developed by direct regeneration of secondary raw materials without the use of thermochemical and metallurgical methods, which is protected by the patent of Ukraine and the patent of Germany. A new solid alloy, obtained by recycling of the tungsten-nickel conversion alloy scrap with the addition of cobalt, was developed, investigated and made for the first time. The basic possibility of using shock-wave processing as a physical factor stimulating the destruction of powder products of any configuration is shown in order to obtain a high-quality powder for the further formation, sintering and production of a tool for various purposes. The theoretical and experimental researches which were carried out, were used to make batches of the tools from the first developed new solid alloy. The proposed devices for the fragmentation of hard alloys and developed methods for the preservation of shock-compressed substances have found practical implementation in the works on the regeneration of hard alloys at Dnipro University of Technology, the State Engineering Center of hard alloys "Svitkermet" and Svitlovodsky State-owned combine of hard alloys and refractory materials. In-dustrial tests have shown that the grinding process time of the powder treated with the explosion is over 20 times less than of the existing grinding technology, which contributes to reducing the energy consumption of the grinding process in only one aggregate at 7.75 MW. The manufactured industrial batches of the min-ing tool using the newly developed technology were introduced in the production conditions of the mines of the Western and Central Donbass, OJSC "Drogobych Dipper Plant", the South Machine-Building Plant, the Dnipropetrovsk Metal Production Association, the State Engineering Center of solid alloys “Svitkermet” and at the Tungsten Scientific Production Enterprise Ltd. The break-even level of the site is reached at the level of sales of 11 tons per year. With a decrease in prices for the finished products by 10-20%, increase in the cost of basic materials by 20-50%, the profitability of products reaches the level of 60-70%. The technology is fundamentally different from the existing ones by high technical and economic indicators, productivity, low energy consumption and environmental cleanliness. The ecologically pure technology of superhard materi-als processing, metal-ceramic components of outdated military equipment and various types of ammunition is suggested.
