| Abstract Scope |
Additive manufacturing can be used to produce custom and replacement parts for power generation at reduced costs and lead times compared to traditional subtractive manufacturing. Power generation components must be able to withstand elevated temperatures and long service lives, indicating the importance of understanding long-term microstructure stability and creep performance. This work evaluates the creep performance of gas-metal arc directed energy deposition (GMA-DED) and laser powder bed fusion (L-PBF) processed 316L. Creep anisotropy is investigated in the GMA-DED and L-PBF samples and the results are compared to that of wrought 316L and 316H tested parallel and perpendicular to the rolling direction. The creep life, creep ductility, and minimum creep rate are used to determine creep stress exponents for each condition. The effect of carbide and intermetallic formation during creep on microstructure stability is investigated, and the outlook for employing additively manufactured stainless steels for creep limited applications is discussed. |
