## Description

- description: 'Fourteen Fe–Cr–Al alloys with systematically varied Cr and Al compositions
    were irradiated at 350 °C to 0.24 dpa by 10.5 MeV self-ions as model alloys for
    the Fe–Cr–Al (oxide dispersion strengthened: ODS) alloys being developed as accident
    tolerant fuel (ATF) cladding for light water reactors. Three dose rates (8 ×10−6,
    8 ×10−5, and 8 ×10−4 dpa/s) were selected to predict the formation behavior of
    Cr-rich precipitates (CrRP) under neutron irradiation conditions. The effects
    of Cr, Al composition, and dose rate on the CrRP formation behavior were evaluated
    using a three-dimensional atom probe (3DAP) analysis. The the CrRP number density,
    volume fraction, and Cr concentration increase with increasing Cr composition,
    decreasing Al composition, and decreasing dose rate. Multiple regression analysis
    showed that in addition to these primary effects, there was an interaction between
    them on the CrRP volume fraction: (1) the higher the Al composition, the smaller
    the increase in the CrRP volume fraction with increasing Cr composition, and (2)
    the lower the Cr composition, the smaller the increase in the CrRP volume fraction
    with the decreasing Al composition and dose rate. '
