| Abstract Scope |
Wire Arc Additive Manufacturing (WAAM) is a novel approach to produce metallic parts with meter-length dimensions. As an additive manufacturing method, WAAM inherits the possibility to tailor properties on a layer-by-layer basis through the selection of process parameters as well as the use of dissimilar alloys. In this study, we focus on the mechanical characterization of bi-metallic parts produced through WAAM. Specifically, we focus on the combination of 316L austenitic stainless steel and low alloy ER70S-6 consumables. The dissimilar fusion boundary and diluted layers between these two alloys exhibits a highly heterogeneous microstructural composition, including islands of martensite and bainite alongside Type I and Type II boundaries. The present work determines the effect of the heterogeneous microstructure on the joint fracture and fatigue performance of bi-material structures. The results provide valuable insights into the mechanical properties of functionally graded components for their qualification in structural applications. |
