The main direction of scientific activity:

Investigation 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. This scientific direction is realized by studying the processes that occur when exposed to tungsten-containing materials of the combination of gaseous media during sintering, thermal power load, the use of high pressures (up to 10 GPa) and temperature (up to 1700 ° C).

Modern laboratory equipment is used in the department to achieve the set scientific and applied tasks. The results of developments are verified in the conditions of experimental and industrial production of batches of products.


Additive Technologies Laboratory

Curator of the laboratory

Matviychuk Alexander Alexandrovich

Candidate of Technical Sciences


 The department has a laboratory "Additive Technologies", whose main task is the 3D printing of blanks of cermets and other related materials for instrumental and structural purposes. Research and development of PDS (Printing / Debinding / Sintering) processes are carried out, which include: Thermoplastic 3D printing of carbide blanks filled with carbide mixtures such as WC-Co, WC-Ni or (Ti, W) C-WC-Co, distillation binder printed blanks, their normalizing and liquid-phase sintering. To do this, work is carried out to select the components of the binder system, optimize their composition, study their filling with carbide mixtures and determine the rheological properties; production of filaments filled with thermoplastic mixtures for layer-by-layer 3D printing, testing of printing parameters, testing of distillation and sintering modes.

Accordingly, optimization is carried out with the help of computer modeling of physical and mechanical properties of filled filaments from the type of binder, the type of filler and the degree of filling, the study of compaction processes during sintering.

To determine the main parameters of the microstructure and physical and mechanical properties of sintered samples of tungsten-containing composites, there is a Metallographic Laboratory.


The mans of the lab are:

  • improvement of methods of metallographic analysis of the structure of hard alloys and tungsten-containing composites;
  • research of processes of structure formation and physical and mechanical characteristics of hard alloys and composite materials, determination of influence of different stages of technological process of production of sintered powder composites on them;
  • providing an assessment of the quality of carbide products, substantiated expert opinions and recommendations for improving the technological processes of obtaining high-quality carbide products;
  • study of the microstructure of samples from heavy alloys such as universities, steels, aluminum alloys, study of the structure of welded joints.

Mathematical and computer modeling


The main direction of research is the development of the theory of strength and plasticity of modern hard alloys using mathematical modeling methods, algorithms which are based on the fundamental principles of physical materials science (dependence of plastic deformation of hard alloy on average phase sizes). -plastic composite materials (determination of elastic modules, coefficients of thermal expansion, residual thermal stresses), diffusion theory.

The created mathematical models allow to analyze the connection of microstructural parameters with the mechanical properties of modern hard alloys, and the programs can be used as an effective tool in the development of new materials.

The adequacy of qualitative and quantitative reflection of the proposed mathematical model of the characteristics of deformation and fracture of real hard alloys is confirmed by many new experimental results of domestic and foreign manufacturers (Plansee Tizit GmbH, AB Sandvik Hard Materials and others).
