Scientific principles for the design of the fundamentally novel class of materials - multi-element alloys (including high entropy ones) with the controlled structure and advanced set of physical, mechanical and functional properties (that combine high temperature strength and low temperature plasticity, heat resistance, shape memory behavior etc. in particular), which are competitive in comparison with known traditional alloys, have been created.

For the design of the new generation of multi-element alloys, composite materials based upon them and multi-component intermetallics and compounds, high entropy coatings, there peculiarities, that include high entropy, crystal lattice distortions and special nano-cluster structure, have been used. It allowed to develop a number of structural and functional materials possessing unique set of properties.

Part of the practical applications of these materials directed onto import substitution of the materials critical for Ukraine have been developed according to orders from end-users ‒ Ukroboronprom factories: design bureau "Pivdenne", design bureau Ivchenko-Progres, Ukrinmash. Besides, orders of the companies from USA (the Boeing company), PRC and South Korea have been also accomplished.
