The main results of his academic activities are related to the development of technological basics for the creation of superelastic titanium-based allows for highly biocompatible bone implants.

As a result, the composition of the Ti-Zr-Nb alloy: 18% of zirconium and 14...15% of niobium (in at.%) was developed and experimentally substantiated. This composition demonstrates the best complex of functional properties: high crystallographic resource of reversible deformation (6 %), superelastic behavior at the temperature of the human body and high resistance to corrosion. The technological basics of melting high-quality ingots from alloys based on the Ti-Zr-Nb system of large weight (over 10 kg) for industrial application by vacuum melting methods were developed.

The technological basics were developed, and the modes of thermomechanical treatment of alloy ingots based on the Ti-Zr-Nb system of large weight for obtaining semi-products in the form of rod and sheet bars with the best complex of properties providing for high biocompatibility were determined. Thermomechanical treatment covers a combination of progressive methods of metal pressure processing (longitudinal and radial-displacement rolling, rotary forging) as instruments of plastic deformation of solid material in combination with a thermal impact.

The technological basics for obtaining permeable porous materials from alloys based on the Ti-Zr-Nb system using methods of traditional powder metallurgy (removable pore former method) were developed. The materials obtained that have the effective porosity of 50-70 % and a very low elasticity module of 3-15 hPa, the same as with the bone tissue, contribute to the germination of the bone tissue at the place of “implant-bone” contact, thus ensuring a reliable mechanical connection between the implant and bone tissue.

The development of the fundamentals for technologies of melting, thermomechanical treatment and powder metallurgy of Ti-Zr-Nb alloys includes comprehensive studies of the structural and phase state of the material, its mechanical and functional properties and corrosion-electrochemical behavior with the use of modern methods of research and tests of metallic biomaterials. Based on integrated studies of the structure and properties, the most appropriate methods of materials treatment were determined.

Regularities of the formation in the material of the structure encouraging its superelastic behavior resulting from the thermomechanical treatment that includes a cold deformation by rolling and post-deformation annealing were examined; special aspects of the impact of the structure on functional features of the Ti-Nb system alloys were established; and the correlation between the structure of austenite and the stability of mechanical (superelastic) behavior of Ti-Nb-Ta and Ti-Nb-Zr alloys in the course of comprehensive thermomechanical tests was discovered.

Regularities of mechanical behavior of the nickel-free shape memory Ti-22Nb-6Zr (at.%) alloy in the conditions of mechano-cycling with deformations in the elastic (with the εс amplitude of <0.3%) and superelastic (εс≥0.3%) areas were established. The maximum longevity in the elastic deformation area is demonstrated by the materials with the structure of strong residual deformation cold working. The maximum longevity in the superelastic deformation area is demonstrated by the materials with polygonizing (nanosubgrained) substructure of strong residual deformation cold working, whose advantage is increased as the deformation amplitude grows.
