Titel
Explosive compaction of metallic-glass powders
Abstract
Rapidly Quenched Materials, produced as powders, flakes or thin strips, can be consolidated making use of high pressures of detonating explosives. The underlying process is a shock front proceeding at a velocity greater than the sonic velocity of the material, which compacts the material instantaneously. Heat generated at particle surfaces can lead to a welding between the individual particles. Due to rapid cooling, the welded areas can be kept amorphous. Powders and chips taken from amorphous filaments show a different behavior in explosive compaction.
