- Abstract
In this study, a numerical model was developed using the Smoothed Particle Hydrodynamics (SPH) method in ANSYS-Autodyn-2D to investigate the bonding phenomenon of the AZ31B-Al5052 explosive joint. The experimental bonding interface shows straight and wavy structures consistent with the simulation. X-ray diffraction (XRD) detected the development of an intermetallic (Al12Mg17) compound at the interface. Due to substantial plastic deformation, the microhardness of post-weld AZ31B (92 HV) and Al 5052 (85 HV) close to the interface was increased by 21% and 25%, respectively. The shear strength (111 MPa) and ram tensile strength (173 MPa) of the AZ31B-Al5052 weld were greater than the weaker parent alloy. The pressure, velocity, and temperature developed during the AZ31B-Al5052 explosive welding were determined by simulation and correlated with the empirical relations.
