▼a The objective of this thesis is to understand the role of pre-implanted helium, with and without the presence of excess carbon, on the cavity evolution of ion-irradiated T91. Alloy T91, heat C2269, was pre-implanted at room temperature with heli |

▼a The swelling, precipitate, and dislocation evolution for the excess carbon and nominal carbon conditions for all helium concentrations was characterized. Scanning transmission electron microscopy (STEM) was used to characterize the microstructur |

▼a In the nominal carbon conditions, swelling decreased with increasing helium concentration. At low helium levels (0, 1, and 10 appm), the cavity evolution was determined by the cavity sink strengths. Differences in density were observed at 50 dpa |

▼a In the excess carbon conditions, swelling was peaked at 10 appm He. The main role of carbon was to inhibit cavity nucleation, which reduced the cavity density at all damage and helium levels compared to the nominal carbon conditions. Additionall |

▼a This work provides substantial insight into the complex evolution of cavities at various helium and carbon levels. |
