Abstract Scope |
Additive manufacturing (AM) can produce unique microstructures and geometries that cannot be manufactured conventionally. AM is used with many materials, but stainless steel alloys are some of the most widely used in industrial applications. For example, 316H SS is being considered for use in the Transformational Challenge Reactor (TCR), a 3D printed nuclear reactor. In this study, 316H SS lattice structures were additively manufactured using a GE Concept Laser Mlab 100R system. The phases and the chemical distribution of the AM 316H SS were determined using EBSD, XRD, and EDS. Additionally, the mechanical behavior and other properties were measured. Unexpectedly, we found that additively manufactured 316H SS has magnetic properties, something not typical of 316 stainless steels. We present observations about the microstructure, magnetic properties, and other behavior of AM 316H SS. This research will help inform future work on AM 316H SS for use in the TCR and beyond. |
