Abstract
Thin-multilayer Ti/Al laminates were prepared by one-step explosive bonding method to investigate the interface bonding and mechanical properties owing to their potential application in aerospace and auto industry. It was found that Ti/Al laminates prepared at the detonation velocity of 2100 m/s exhibited superior surface quality without any defects in comparison with other detonation velocities owing to the optimum explosive pressure and impact velocity. The interface morphologies and element distribution of Ti/Al laminates prepared at the detonation velocity of 2100 m/s were characterized by means of SEM and EDS. The results indicated that the linear and wavy bonding interface coexisted and element diffusion occurred in the interfacial zone. Furthermore, thin-multilayer Ti/Al laminates possessed high microhardness, excellent interlaminar shear and tensile properties.
