Energy and deformation during explosive compaction of CuCr alloys

The explosive impact energy is composed of the tube deformation energy and the powder compact energy. The explosive impact energy is calculated by means of the kinetic energy of the steel tubes, while the tube deformation energy is dependent on the real deformation extent of the steel tubes. The relationships between the energy and the deformation during explosive compaction of CuCr alloys have been found. The results show that, with the rise of the impact energy, the compact energy increases synchronously, while the deformation energy and the deformation extent of the tubes hardly change. If the explosive mass is too large, the compact energy is so large that the formation of the Mach reflection takes place, resulting in the compaction billets with low densities.
