Explosive Compaction of Powders: Principle and Prospects

It is the wish of each powder metallurgist to posses presses with great capacities developing high pressures. Hard powders are especially difficult to compact. For this reason, the Hot Isostatic Pressing procedure was developed. Explosive Compaction on the other hand has the potential of developing very high pressures, dynamically applicable to powders. Its achievements include not only relatively high densities for green compacts(approximately 100% of theoretical density), but also the possibility of creating new materials. The main features of the method are explained and a survey of the latest developments is given. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
