Investigations of explosive consolidation technology of nano sized Al, ultra-disperse Ni and Ti powder compositions are discussed. The mixtures of ultra-disperse Ti (Ni) - nano sized (<50nm) Al powder compositions were consolidated to full or near-full density by explosive-compaction technology. The emulsion and ammonium nitride based industrial explosives were used for generation of shock waves. To form ultra-fine grained NiAl and TiAl intermetallides with different compositions, ultra-disperse Ni and Ti particle...

An Investigation of explosive consolidation processes of W-Cu ultra-disperse and nano sized powder compositions are discussed. For theoretical calculations of the explosive loaded materials were used the hydrodynamic theory and experimental adiabatics of W and Cu. The stress-deformed state of the steel ampoule-containers was estimated using the solutions of elasticity theory. Copper tungsten (W-Cu) powder compositions were consolidated to full or near-full density by explosive-compaction technique. The industrial ...
