| Abstract Scope |
A few solid-state methods that employ high shear and shear rate at the interface have recently demonstrated viable bonds between “immiscible” pairs of Mg and Fe systems with and without the need for alloying elements. What might be the joining mechanisms responsible for bonding? We report on interface characteristics of bonded Mg-Fe interfaces made using Friction stir assisted scribe technique (FaST) to answer this question. The interface region consists of highly refined nano scale grains, Al and O segregation and intercalated regions. We will discuss latest results from micro and nano scale interface characterization including TEM and APT results for alloy and pure metal combinations and present joining mechanisms hypotheses and associated challenges in interpreting results. |
