| Abstract Scope |
Wire + Arc Additive Manufacturing (AM) is a promising solution for large scale components, which enables fully-dense, near-net shape builds achievable throughout a vast array of alloy families. These material and geometrical flexibilities allow for multi-material AM and functional grading. Nevertheless, the dissolution of the tailored composition of a welding wire in a dissimilar weld deposit may lead to an undesirable material matrix with unexpected effects on the overall product’s performance. In this work, the interface region between a multi-bead deposit of high-strength S460 structural steel and an austenitic stainless steel 316L is studied. Extensive EBSD, EDS and XRD characterization are used to study the interface behavior, which clearly distinguishes itself from the neighboring material of nominal composition through the formation of a hard martensitic matrix alongside retained austenite. This work establishes a base for further studies of the mechanical properties of these graded components. |
