Project summary

The principal novelty of scientific and technological solutions proposed by the project consists of preparing and using coated powders and technology of hot shock wave treatment in the compacting process.

Utilization of coated powders in technology of shock-wave compacting in comparison with mechanical mixtures has some advantages and promotes the obtaining of consolidated samples with high values of strength properties and uniformly distributed bounding phase which from the other hand provides high value of plastic properties.

As investigation show at high temperatures (400–1200 °C), under the influence of pressure 10–20 GPa there occurs on the shock-wave’s front a melting of the plated layer and inpidual particles are subject of all-around hydrodynamic compression. As a result of this a deformation mechanism is put into action which is characteristics for super-high pressures (100 GPa and more).

All this causes significant changes of structures and properties of obtained compacts. The produced samples are distinguished by a high strength and sometimes by unusual structures.

High density, uniformity of the bonding distribution , perfect structure are those principal characteristics which provide an obtaining of high strength compacts.

The key of the project is factory at A/O Composite Materials which produce the different type of coated powders and universal half-automated experimental Robot (UHAR). The UHAR allows to compact and to treat powders and bulk materials in the range of temperature 20–1300 °C, at intensity of loading 0.5–30 GPa.

The project foresees to investigate various types of coated powders Ni-Me, Ni-carbide, Co-Me, Co-carbide, Cu-Me, Cu-carbide under the wide range of static and dynamic conditions of compacting.

The results of investigation will be published in scientific papers. The final report and pilot samples will be prepared for ISTC.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
