Abstract Scope |
To use laser powder bed fusion (LPBF) 316H stainless steel in high-temperature nuclear reactor applications, research efforts are needed to develop laser processing conditions and proper heat treatments of the material to yield optimal material properties. This study focuses on the LPBF of 316H via a Renishaw AM400 machine. A total of 105 test cubes were printed with different combinations of laser power, point distance and point exposure time. The process of down-selection was based on the density/porosity of the samples. Using the optimized process parameters, larger block materials were fabricated for further heat treatments, microstructural analysis, and subsequent high-temperature tension, creep and creep-fatigue testing. The results are an important first step towards the qualification of LPBF 316H for reactor applications. |
