The joining of magnesium and aluminium alloys by inclined arrangement of explosive welding

Multi-material lightweight frames are growing rapidly in a variety of industries, specifically where weight reduction, performance improvement, and cost savings are required. Magnesium alloys (AZ31B) fulfil the requirements, but they are prone to corrosion. The joining of magnesium and aluminium alloys is being suggested as an effective approach to this issue.In this study, aluminium alloy and magnesium alloy plates were joined successfully through the inclined arrangement of the explosive welding method. The interface microstructure and mechanical properties of joined plates were examined. The microstructural studies illustrated the development of a wavy interface with the Al12Mg17 intermetallic compound. The maximum microhardness values were obtained close to the interface due to extreme plastic deformation. The shear strength and ram tensile strength of the Al 5052/AZ31B welded plate were obtained 93 MPa and 146 MPa, respectively.
