The change in the hardness of LCAC, TZM, and ODS molybdenum in the post-irradiated and annealed conditions

Hardness measurements were performed on wrought Low Carbon Arc Cast (LCAC), TZM, and Oxide Dispersion Strengthened (ODS) molybdenum in the post-irradiated and post-irradiated + annealed condition to determine the recovery kinetics. Irradiations performed in the High Flux Isotope Reactor (HFIR) at no...

Zusammenfassung:Hardness measurements were performed on wrought Low Carbon Arc Cast (LCAC), TZM, and Oxide Dispersion Strengthened (ODS) molybdenum in the post-irradiated and post-irradiated + annealed condition to determine the recovery kinetics. Irradiations performed in the High Flux Isotope Reactor (HFIR) at nominally 300 °C and 600 °C to neutron fluence levels that range from 10.5 to 246 × 10 24 n/m 2 ( E > 0.1 MeV) resulted in relatively large increases in hardness (77–109%), while small increases in hardness (
