摘要：
The AZ31B/6061 alloy composite plate is fabricated by explosive welding, as the base plate of AZ31B magnesium alloy material and the flyer plate of 6061 aluminum alloy material. The macro/micro-structure, elements diffusion and bonding strength of the composite bonding interface. The results show that the bonding interface presents a periodical wave; near the bonding interface the plastic deformation is serious and microstructure in the form of twin and recrystallization mainly; adiabatic shear bands are found on the AZ31B Mg alloy side adjacent to the interface by the direction of 45° and the microstructure is fine grain microstructure by recrystallization; the micro-hardness distribution characteristics is decrease with the increase of distance from the bonding interface both of AZ31B and 6061 plate; the interface bonding strength is 193.3 MPa and the bonding mechanism of pressure welding, diffusion welding and local melting welding. © 2016 Journal of Mechanical Engineering.
