Article Preview

The interface is the area where two type of materials are connected, the strength and property of interface are important for the application of the clad. In this paper, interfacial strength and fracture properties of stainless steel-aluminum clad are analyzed with the methods of interfacial shear test and four point bending test, and the interfacial crack and the interfacial fracture structure are analyzed with SEM. The results show that the bonding of stainless steel and aluminum is successfully realized by explosive welding, the interfacial shear strength reach 70.90MPa, and the interfacial energy release rate is 1.725 MPa•m, the thickness of transition layer is about 10μm at the interface, the interfacial fracture happen and extend in the transition layer along the interface and the interface fracture structure is inclined to brittle fracture.
