Microstructure characteristics and performance of dissimilar welds between magnesium alloy and aluminum formed by friction stirring

Abstract The friction stir welding of AZ31Mg/1060Al has been investigated. The welds were formed when the stirring pin was off the centerline to AZ31 or to 1060, and are characterized by intercalation lamellae. Al 3 Mg 2 and Al 12 Mg 17 cause the weld to crack during friction stir welding on the centerline of the weld.
