Abstract

The fragmentation during explosion welding is briefly reviewed. Fragmentation of partitioning type (FPT), which consists in partitioning into particles that either fly away or join each other, is detected. FPT is an analog of the fragmentation during an explosion that was studied by Mott. In both cases, the flight of particles (fragments) takes place, and the integrity of the material is retained in FPT. FPT is a powerful channel for the dissipation of supplied energy, since the surface of flying particles has a large total area.
