| Abstract Scope |
The objective of this talk is to understand the effects of neutron irradiation on the microstructure and mechanical properties of Inconel 625 (IN625) fabricated using powder metallurgy with hot isostatic pressing (PM-HIP). PM-HIP presents an attractive alternative to traditional manufacturing methods for use in nuclear applications, however its irradiation response must first be understood. IN625 fabricated with PM-HIP and a traditional forging method were neutron irradiated to a dose of 1 displacement per atom (dpa) at 300ºC in the Advanced Test Reactor. Post-irradiation examination involved bright field transmission electron microscopy (BFSTEM), atom probe tomography (APT), nanoindentation, and in-hot cell tensile testing. PM-HIP IN625 is less susceptible to void nucleation than its forged counterpart, and it additionally shows less irradiation-hardening and embrittlement. The results of this study are a step forward in demonstrating the viability of PM-HIP materials in nuclear applications. |
