Abstract:The effect of Al/Zn/Cu binary and ternary solid solution phase constituents on metallurgical and mechanical properties of Al/Cu dissimilar friction stir welding using Zn as an alloying element was investigated. Because of Zn interlayer material binary intermetallic compounds (IMCs) such as AlCu, Al 2 Cu, Al .71 Zn .29 , CuZn 5 and ternary IMCs such as Al 4.2 Cu 3.2 Zn .7 are formed. These solid solution alloying phase constituents improved the weld properties of the joint. The tensile strength was enhanced by … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
