Metallic clad plates have a widespread application in nuclear power plant for safety injection tank.A novel bi-layers steel clad plates comprising of austenite stainless steel and low carbon steel has been successfully fabricated by hot rolling at high temperature.Microstructural observation shows a gradient transition interfacial layer with the size of about 80~100μm,which is attributed to the thermal diffusion of C,Cr,Ni elements during the roll bonding process.The stainless steel clad plates exhibit a high ultimate tensile strength(505MPa)and high uniform elongation(36%).Fracture morphologies show that interfacial delamination,tear ridges and intergranular fracture characteristics presented at the interfacial zone.There are many dimples with large and fine sizes exhibited in the carbon steel layer and stainless steel layer,respectively,which is advantageous for the toughening effect of stainless steel clad plates.
