Scientific direction
Study of the influence of sintering conditions and additional chemical-thermal and thermomechanical treatments on the formation of structural and physico-mechanical properties of tungsten hard alloys and other composite materials based on tungsten for instrumental and structural applications. The specified scientific direction is implemented by studying the processes that occur when tungsten-containing materials are exposed to a combination of a gas environment during their sintering, thermal load, and the application of high pressures (up to 10 GPa) and temperatures (up to 1700 °C).
