Abstract Scope |
Ability to weld Inconel with stainless steel would enable design simplification for various high temperature applications. Fusion welding and plastic deformation based solid-state joining techniques lead to intermetallics and significant deformation zone, respectively, which lead to inferior joint performance. In this work, rotary friction welds of In-600 and SS316L are performed with and without Cu interlayer, at 2000 rpm, 5 mm/min friction feed rate and 25 mm/min plunge feed rate. Mechanical interlocking and 300 to 400 microns thick deformation zone is observed in the joints made without interlayer. No grain refinement is noticed in joints with Cu interlayer. Further, intermetallics are not observed at Cu and In-600 interface, as Ni and Cu form an isomorphous system. Tensile testing results show that a Cu interlayer leads to improved joint performance. Fractured surfaces from tension tests are characterized and damage is discussed. |
