Project summary

It is proposed to develop the method of explosive transformation of boron-nitride graphite like modifications into dense ones. Also tile explosive compaction systems for original powder of dense boron like modification, diamond and other hard materials to be turned into polycrystal state with the characteristics approximately reaching the monocrystal ones are proposed to be developed.

For a long time the superhard material compaction has been an urgent problem, but it still has no satisfactory solution. Statistical approach failed and the attempts of dynamical (explosive) methods applying are in its infancy. By now extremely encouraging results are obtained both in this country and abroad (for example, in LLNL, USA), results which give confidence in possibility of this problem resolving.

One of the possible applications is manufacturing of cutting tools.

The objective of the proposal is in conformity with the ISTC's objectives in what is connected with redirecting the efforts of mass destruction weapons scientists as well as supporting fundamental and applied R&D for peaceful purposes (in the present case-in the field of material science).
