Authors developed novel structural and functional multi-component high entropy materials that possess high scientific, technological and innovative constituent together with high competitiveness (in particular, combination of high temperature strength, low temperature plasticity, heat resistance, advanced functional properties of shape memory alloys etc.) comparing with known traditional alloys.

High entropy, presence of the crystal lattice distortions and specific nano-cluster structure have been used as essential peculiarities for the development of the novel generation of multi-component alloys, composite materials. It allowed to obtain a row of novel materials with the unique set of properties.

Tasks for practical application of these materials directed onto import substitution of the materials critical for Ukraine have been carried out 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) and PRC have been also accomplished.
