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 made 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 “immiscible” pairs of Mg and Fe. We present first direct experimental evidence of presence of oxide layer, Al segregation by APT and nano steel grains close to interface by TEM study.Revised: February 24, 2021 | Published: January 15, 2021
