Abstract

The technique of explosive consolidation was used to prepare cermets of boron carbide with aluminium and 7075 aluminium alloy. Compacts were produced by application of 10-12 GPa pressure which was induced by explosive detonation. The compacts obtained exhibit high hardness-increasing with an increase in the boron-carbide content, integrity and close to theorical density. Hardness, fracture toughness and flexural strengths of the composites produced indicate extensive shock hardening of the metal (or alloy) matrix during consolidation.
