  text: <jats:title>Abstract</jats:title><jats:p>Due to its excellent biocompatibility,
    pure iron is a very promising implant material, but often features corrosion rates
    that are too low. Using additive manufacturing and modified powders the microstructure
    and, thus, the material properties, e.g., the corrosion properties, can be tailored
    for specific applications. Within the scope of this study, pure iron powder was
    modified with different amounts of CeO<jats:sub>2</jats:sub> or Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>
    nanoparticles and subsequently processed by Electron Beam Powder Bed Fusion (PBF-EB/M).
    The corrosion-fatigue behavior of CeO<jats:sub>2</jats:sub> and Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>
    modified iron was investigated using rotation bending tests under the influence
    of simulated body fluid (m-SBF). While the modification using Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>
    showed reduced fatigue and corrosion-fatigue strengths, it could be demonstrated
    that the modification with CeO<jats:sub>2</jats:sub> is characterized by improved
    fatigue properties. The superior fatigue properties in air are attributed to the
    positive impact of dispersion strengthening. Additionally, an increased degradation
    rate compared to pure iron could be observed, eventually promoting an earlier
    failure of the specimens in the corrosion fatigue tests.</jats:p>
