MICROSTRUCTURES IN NEUTRON IRRADIATED Fe-Cr-Ni-P-Ti MODEL AUSTENITIC ALLOYS DOPED WITH ~(10)B

摘要

Fe-16Cr-17Ni ternary alloy and those with addition of 0.024P, 0.1P and 0.1P+0.25Ti were irradiated with fast neutrons in FFTF/MOTA at 793 K and 874 K to 33 dpa and 60 dpa. For the purpose of investigating helium production effect, two levels of ~(10)B were doped for each alloy. The microstructures and their relation with tensile properties were examined. The yield stress change was correlated with the density of phosphide precipitates.
