EXPLOSION BONDED CLAD PLATE
Explosion bonded plate is a new type of composite material, which is made of two layers of metal plate welded by explosion. This material has high strength, high toughness and excellent protective performance, and is widely used in the military, aerospace, automotive and construction fields. It can be welded and performed at large area. The two layers of metal plates can be the same metal or different metals. One metal plate can be welded in a "cover" way to another metal plate. During production process, explosive quantity is much more important, which explodes in a safety environment. During the explosion welding process, the explosion produces high temperature and high pressure to make the two metal plates to quickly squeeze into each other and form chemical bonding. At the same time, due to the inertia and recoil force of the explosion byproduct, a very uniform interface is formed between the two metal plates, and there are a large number of microstructural defects on the interface.

These microstructural defects include dislocations, twinning, grain boundaries and so on. They have important effects on both the mechanical properties and the protective properties of the materials. For example, the dislocation can increase the plastic deformation ability of the material, the twinning can improve the toughness and fracture toughness of the material, and the grain boundaries can effectively block the expansion of cracks.
