Among several processes of industrial metalworking the explosive compaction of powders still is of innovative character. The consolidation of powders per se is not the decisive factor. Besides high green densities achieved in green compacts structural changes caused by the shock wave are of importance. There is enhanced activation and chemical reactivity and the possibility of achieving metastable phases. Some examples are outlined in this paper.
