Multilayer metal composite materials are used in the chemical industry, particularly nuclear power engineering, and enable to increase the robustness and durability of steel structures while reducing their metal consumption. These materials are made of stainless steel, alternating with commercial quality steels, and have increased corrosion resistance, several times greater than the resistance of stainless steel in the material structure.
In this work, the structure formation of the transition layer of a layered metal composite material obtained via explosion welding was studied through the transmission electron microscopy method.
A high concentration of dislocations in the transition layer was established. After the blast exposition, the material retained its crystalline structure and acquired a directional texture.
