One-step explosive bonding preparation and interface bonding property evaluation of titanium/aluminum/titanium laminates with

Abstract:

The morphology and element distribution of the bonding interface were investigated by means of SEM and EDS to evaluate the interface bonding property of titanium/aluminum/titanium with three layers prepared by one-step explosive bonding method. Besides, the tensile property and the bending property were also investigated. The results indicated that the linear and wavy bonding interface coexisted and element diffusion occurred in the interfacial zone. Meanwhile, the tensile and bending test results showed that as-prepared Ti/Al/Ti laminates had a high strength and excellent bonding property and could endure a large secondary plastic deformation.
