| Abstract Scope |
The use of additive manufacturing in aerospace and the nuclear industry is growing rapidly and the importance to standardize manufacturing process has also been realized. The materials manufactured using additive manufacturing requires characterization at microscale due to microstructural features formed during localized heating in the manufacturing process. Nanoindentation has emerged as a robust and repeatable technique to detect and characterize mechanical properties and deformation behaviors at the microscale. In this work, mechanical properties of conventionally forged Inconel 718 were compared with the additively manufactured Inconel 718 at room temperature and elevated temperatures of 350C and 650C. Selective laser melting was used for additive manufacturing of Inconel 718. The mechanical properties including hardness, reduced modulus and creep rate were obtained using Nanoindentation technique. Compared to room temperature, the decrease in the reduced modulus and hardness for additively manufactured samples was lesser than the conventional sample at 650C. |
