Summary of past research

Since 70s I and my team have been carrying out theoretical and applied investigations in the field of phase and structural transformations in metals and alloys under highly non-equilibrium conditions. An approach which consists of the use of controlled microscale inhomogeneity of high-temperature solid solutions for optimization of phase composition, microstructure and, as a result, properties of structural materials was developed and novel technologies for aerospace and other industries were developed with this approach.

From 1977 to 1991 I took part in defense research programs under contracts with Ministry of Aviation Industry of USSR (development of materials and technologies for aircrafts and missiles).

Since 1990, I have been carrying out research program in field of powder metallurgy of titanium alloys and titanium aluminides, in particular investigation of phase and structural transformations on synthesis of these materials using elemental powder blends.

In 1989-2012 I have been teaching courses “Physics of Phase Transformations”, “Structural Phase Transformations” and “Advanced Aerospace Materials” in the Department of Physics in Kyiv National University.

Main areas of interest

Solid State Physics, Physics of Metals, Physics of Strength and Ductility, Phase and Structural Transformations, Aerospace Materials.
