| Abstract Scope |
The objective of this talk is to understand the role of irradiation dose and temperature on microstructure evolution and mechanical properties of a Ni-based alloy produced by powder metallurgy with hot isostatic pressing (PM-HIP). PM-HIP is an attractive alternative to castings and forgings in the nuclear industry because components exhibit chemical homogeneity and are produced near-net shape, but the integrity of PM-HIP components under irradiation must first be understood. Inconel 625( IN625) manufactured with PM-HIP is irradiated with 4.5 MeV Fe+ ions to 50 and 100 dpa at 400°C and 500°C; conventional forged IN625 is also studied as a control specimen. Nanoindentation is used to evaluate yield strength of the irradiated layer. Microstructure is characterized using scanning and transmission electron microscopy(SEM, TEM). Irradiation hardening is related to the microstructural evolution through the Orowan model. This study forms the basis for assessing the viability of PM-HIP Inconel for nuclear settings. |
