EXPLOSIVE CONSOLIDATION OF ULTRAFINE NI-AL-TI POWDERS
Abstract
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 particles were mixed with nano-crystalline Al. Each reaction mixture was placed in a sealed container and explosively compacted using a normal and cylindrical detonation set-up. Explosive compaction experiments were performed in range of pressure impulse (3-20 GPA). Structural investigations (SEM) and micro-hardness measurements were used to characterize the intermetallides phase composition and mechanical properties.
