Aluminum based composites find immense potential in automobile, aeronautical and structural applications. Silicon carbide particulate reinforced aluminum composite (Al-SiCp) was shock densified using axisymmetric assemblies for underwater explosions. Underwater shock consolidation using explosives is a viable alternative to the conventional techniques to produce reaction-products-free-bulk materials from difficult-to-consolidate powders. It is a one stage densification process which involves a very rapid and intense deposition of shock energy, released from chemical explosives, on powder particle surfaces. Unidirectional planar shock waves, generated from a high explosive of 6.9 km/s detonation velocity, were applied to obtain uniform consolidation of 30% (by volume) SiCp reinforced aluminum composites. The interfacial modifications, microstructural variations, minimal reactivity during the ceramic reinforcement interaction in the underwater explosive shock consolidated Al-SiCp composite systems are discussed.
