Explosive Compaction of WC + Co Powders with Axial Symmetry

The objective of this work is to develop and optimize explosive compaction techniques for metalbonded solid powder materials. Experiments of explosive compaction of tungsten carbide (WC) and cobalt (Co) powders in cylindrical storage ampoules are conducted. Additionally, numeric simulation of shock waves propagation within the two-phased porous WC+Co medium are performed. Based on experimental and numerical simulation studies of shock waves propagation, optimal conditions of two-phased porous metal-bonded solid powder materials explosive compaction are obtained. It is demonstrated that compaction with the detonation velocity of 4.6 km/s followed by sintering is the most advantageous for obtaining an uniform solid WC+Co powder compact with the volume ratio of 9:1, axial symmetry and central core.
