Project summary

The Project is devoted to investigations in the field of Self-propagating High-temperature Synthesis (SHS). This method allows us to use the combustion processes for synthesizing compounds and designing materials for modern technique. These works were significantly influenced by the experience gained within the investigations of the combustion of explosives, gun powders, solid propellants. Within the investigations carried out in the field of the combustion of these condensed materials, the "solid flame" phenomenon was discovered and the SHS method was created by the researchers of the Academy of Sciences of the former USSR.

Presently, the SHS is a global problem which was significantly developed in the USA, Japan, Western Europe. The significant achievements within this field belong to American and Japanese scientists. The Americans pay great attention to the theoretical basis of the SHS method. The Japanese researchers prefer the problem of practical application of this method for creating new technologies.

The early efforts of Russian and foreign scientists were aimed at obtaining pure homogeneous SHS products. But recently, in the field of the Material Science the opposite problems appeared, since it was disclosed that some types of inhomogeneous materials were characterized by better operation parameters. Now two classes of such materials are known: microinhomogeneous (composites) and macroinhomogeneous materials (multilayer, gradient). Their production is an original and very important problem. The SHS appeared to be a very effective process for obtaining inhomogeneous materials. Now the progress is evident in the production of composite powders.

The Project is devoted to special, purposeful investigation of the terms of various inhomogeneous materials production by the SHS.

It includes the following stages:

- study of inhomogeneous structure formation mechanism;
- determination of optimum conditions for synthesizing micro- and macroinhomogeneous materials of various classes and purposes;
- additional treatment of inhomogeneous SHS products with obtaining final items;
- investigation of composition, structure and properties of inhomogeneous SHS materials;
- search of more effective application field for the items produced from inhomogeneous SHS materials.

Within the Project the following groups of inhomogeneous materials will be studied:

- powders, materials, items, and coatings based on TiC, SiC, TiB2, CrB2, Si3N4 in various combinations and with different properties;
- materials of STIM group (hard alloys);
- advanced ceramics based on Si3N4, SiC, AlN, TiB2, BN;
- materials with coarse-grained fillers of superhard cubic boron nitride.

For carrying out these works, we shall use the SHS technologies: SHS-densifications (including the method realized in gasostats of high pressure), SHS-sintering, SHS-explosion.

The experience and experimental basis of the Institute of Structural Macrokinetics of the Russian Academy of Sciences (ISMAN) and Russian Federal Nuclear Center (RFNC-VNIIEF) will be used.

Potential Role of Foreign Collaborators

Within the Project, the foreign collaborators are supposed to participate in the following investigations: combustion and structure formation mechanism; initial product synthesis and its processing; technological processing of the combustion product; investigation of composition, structure, and properties of the powders, final materials, items, coatings; search of more effective application fields for inhomogeneous materials.
