INVESTIGATION ON THE STRUCTURE NEAR THE INTERFACE OF EXPLOSIVE COMPOSITE PLATE

摘要

The technology of the explosive composition has almost extreme properties such as huge shock high-density plastic deformation and high deformation speed, instant temperature change, state of heat insulation and so on. They lead not only the dislocation density to increase greatly, move and pile but also the vacancy density to increase radically. When the composite metal plate is thin enough, it could be thought that these changes are consistent on the whole thickness section. The result shows that it is possible to obtain the nano-crystal structure film materials and nano-structured block materials by this method. The thickness and properties of the nano-crystal structure materials depend on the factors such as the intensity of explosive shock, the properties of the composite metals, etc.
