| Research Abstract |
The objective of this study is to obtain fundamental knowledge on effect of alloying elements on formation of intermetallic compound layer at the interface between aluminum and steel and the formation mechanism, which is available to precisely control the interfacial reaction during welding of aluminum to steel. In this study, effect of Cu, Ni and Ti on formation of intermetallic compound layer at the interface was examined. These alloying elements hardly affected types of intermetallic compound formed at the interface, but Ti reduced thickness of formed intermetallic layers. Mechanism on the thickness reduction attempted to be clarified, which should be an useful knowledge for highly precise control of interracial reaction during welding of aluminum to steel.
