摘要
The characteristics of bonding strength of hot rolled stainless clad steel were investigated in conjunction with the microstructures and fracture toughness of the bonding interface and the effect of specimen size on bonding strength. The bonding ratio is the most important parameter for evaluation of the bonding interface. The bonding strength and fracture toughness decrease and crack propagation rate increases with decrease of bonding ratio, which results in higher possibility to debond at the interface with T joint welds. The shear and ram tensile strengths insufficiently reflect the characteristics of bonding interface and are affected by the size of test specimen. The fracture toughness and crack propagation rate of the bonding interface change with the strength of clad stainless steel, and residual stress remained in the interface.
