WebShock waves rapidly densify a powder with modest heating and high stresses [95]. If the material is brittle, then preheating is required prior to compaction. Densification is rapid by plastic flow while the material thermally softens from frictional self-heating. An example layout for explosive consolidation is given in Figure 10.42.
