Interfacial reaction during friction stir assisted scribe welding of immiscible Fe and Mg alloy system

Interfacial reaction during friction stir assisted scribe welding of immiscible Fe and Mg alloy system

Abstract We report on interfacial characteristics and chemistry of bonded Mg-Fe interfaces welded using friction stir assisted scribe technique (FaST). Two pairs of dissimilar joints: (AZ31-DP590) and (Pure Mg-DP590) were studied to shed light on joining mechanisms responsible for bonding of “immisc...
