The present disclosure discloses a device and a method for forming a metal plate by using a high-energy electric pulse to drive an energetic material. The device includes high-energy pulse discharge equipment, an intelligent robot arm control system, a vacuum pumping device, a hydraulic press, a forming die, positive and negative electrodes, an energetic rod, and liquid supply equipment. According to the present disclosure, energy of a metal wire is added to energy of an energetic material after energy release to implement high-rate forming of the plate. A discharge voltage of the high-energy pulse discharge equipment is reduced and a service life thereof is prolonged. The discharge equipment is triggered by the manufactured small-size electric pulse metal wire, thereby reducing a volume and costs of the equipment and miniaturizing the equipment to implement precise operating, forming, and intelligent integration with the robot arm control system.

A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.
