Development of methods and innovative approaches for the creation of metal, ceramic and composite materials with specific physical, mechanical and key service characteristics, in particular increased combinations of strength, hardness, plasticity, magnetic and other properties, which provide a qualitative advantage of existing and promising samples of weapons, military machinery and energy equipment.
For the first time in world practice, comprehensive studies of the processes of forming layered structures in titanium-based materials by methods of local (surface) rapid heat treatment and additive manufacturing (powder metallurgy, 3D printing by electron beam using wire) were carried out. On this basis, a range of armor protection elements with a layered structure was created, the advantages of which are twice reduced weight compared to steel armor, and resistance to repeated impact compared to ceramics.
The physical bases and industrial equipment for the innovative technology of 3D printing of titanium alloys and metal-matrix composites with a profiled electron beam have been developed, which surpasses other additive methods with unique opportunities to control thermal fields, kinetics of local melting and crystallization, and the structure of crystallized metal during 3D printing. Thanks to this, high productivity is ensured, while physical and mechanical characteristics of printed products achieved the level of deformed material characteristics.
The technology of electron beam melting of high-strength titanium alloy ingots with diameters from 110 mm to 600 mm, which are supplied to domestic factories, was developed and introduced into industrial production. The technology ensured production of titanium ingots in Ukraine and substitution of corresponding import products.
For the first time, a correlation was established between the parameters of the nanoscale structure of the coatings and the level of strength characteristics of the "base-coating" system, the temperature-time regimes of the formation of nanostructures with the optimal level of physical and mechanical properties. The results of positive approval of new wear-resistant powder alloys of the eutectic type for coatings and their application at domestic industrial enterprises are presented.
A number of new magnetically soft, magnetically hard and high-strength amorphous, nano- and microcrystalline alloys based on iron, cobalt, titanium and aluminum have been developed, which in terms of magnetic, corrosion and mechanical properties surpass the properties of existing analogs of traditional crystalline precision alloys (ferrites, steels, titanium and aluminum alloys, invar, etc.). They are implemented at enterprises of the industrial complex of the electronic, electrical engineering and instrument-making industries in the production of transformers, chokes and sensors using amorphous and nanocrystalline magnetic conductors, including products of special purpose for weapons and military equipment.
