Magnesium alloys, due to their attractive characteristics, are being utilized as lightweight structural materials in aerospace, automotive, and various other industries. Further design flexibility can be obtained by joining the Mg alloys with outstanding performance, such aluminum alloys. In this study, Al-6062 AZ31B have been joined through friction stir welding (FSW) using high-speed steel (H...
