| Abstract Scope |
Laser additive manufacturing (AM) is being considered by the nuclear industry to manufacture net-shape components for advanced reactors and micro reactors. Part-to-part and vendor-to-vendor variations in part quality, microstructure, and mechanical properties are common for additively manufactured components, attributing to the different processing conditions. This study investigates the influence of process parameters and solution annealing heat treatment on the high-temperature creep properties of 316H stainless steel made by laser directed energy deposition (DED) AM. Through creep testing of microstructurally gradient specimens and typical ASTM standard specimens, a significant amount of creep data has been generated. The data has been benchmarked against a large database of wrought material to help determine the fitness for service of AM 316H. Comparing both DED and LPBF, creep life and corresponding mechanisms are compared. Potential factors influencing the vast differences in creep performance will be outlined and discussed in this work. |
