Research Status of Processing Technology of Laminated Metal Composite

Three processing technologies of clad metal composite explosive welding method, rolling cladding and explo- sions-rolling cladding are summarized. Relevant tec, hnology research of the mechanism of explosive welding, ways of initia- tion, preparation of explosives, preferences and etc is described; the hot rolling cladding, cold rolling cladding with con- stant roller diameter and other technical status quo is discussed; the key of the explosion-rolling composite technology is selection of explosive welding parameter, even fraction between the metal layers, determination of the rolling process pa- rameters and so on. The development direction of the layered metal composite materials processing technology is ： the com- plex structure of the material, increase damage tolerance and high composite toughening; functional integration, structural materials and functional materials interpenetration, comprehensive integration; high performance, and further improve spe- cific strength and specific modulus; intelligent, merging materials, structures and electrons; cost reduction-from the past mainly concerned with peribrmance and quality to turn to reduce the cost.
