Rapidly solidified Type 304 stainless steel powders produced by two processes (centrifugal atomization and dissolved gas atomization) were consolidated by stress waves generated by high explosives. The metallurgical characteristics of the powder before and after consolidation are described which include examinations by optical and electron microscopy and microhardness. Particular attention is paid to the differences between the parameters to produce near full density ''green'' compacts and metallurgically fused monoliths. The evolution of the die/target design to produce fully dense, crack-free monoliths is illustrated and pressure-time history as calculated from a two-dimensional hydrodynamic code is presented.
