Microstructures and Tensile Behaviors of Stainless Steel Clad Plate
A novel bi-layers clad plate comprising of stainless steel and carbon steel has been successfully fabricated by vacuum hot rolling at a high temperature of 1100 °C. The microstructure observation showed an interfacial transition zone about 80–100 μm in width, which is attributed to the diffusion of carbon element at the interface. The stainless steel clad plate exhibited a high ultimate tensile strength (578 MPa) and high uniform elongation (52%), and the elastic modulus and stress mismatch at the interface resulted into severe warping resilience phenomenon. Fracture characterizations highlight that the delamination and intergranular cracks presented at the interfacial transition zone.
