| Abstract Scope |
Nuclear energy, along with renewables, is critical for decarbonizing the energy sector. Additive manufacturing technologies like laser powder bed fusion (LPBF) can enable near net shape components for next generation of reactors. However, variability in microstructure and material performance originating from a combination of process parameters, geometry, and powder feedstock chemistry pose a challenge to qualify AM for nuclear energy applications. Here, we quantify the effects of powder feedstock chemistry and process conditions on the microstructure evolution in stainless steel (SS) 316 L and SS 316H fabricated by LPBF. We show that changes in chemistry affect the phase transformation pathways as well as sensitivity of the microstructure to the process conditions. The effect of these variables on the resulting material performance will also be discussed. |
