Abstract The microstructural response of neutron irradiated 3C-SiC have been investigated over a wide irradiation temperature and fluence range via qualitative and quantitative synchrotron-based X-ray diffraction characterization. We identify several neutron fluence- and irradiation temperature-dependent changes in the microstructure, and directly highlight the specific defects introduced through the course of irradiation. By quantifying the microstructure, we aim to develop a more detailed understanding of the radiation response of SiC. Such studies are important to build mechanistic models of material performance and to understand the susceptibility of various microstructures to radiation damage for advanced energy applications.

摘要 通过基于同步加速器的定性和定量 X 射线衍射表征，研究了中子辐照 3C-SiC 在宽辐照温度和通量范围内的微观结构响应。我们确定了微观结构中与中子注量和辐照温度相关的几种变化，并直接突出了辐照过程中引入的特定缺陷。通过量化微观结构，我们旨在更详细地了解 SiC 的辐射响应。这些研究对于建立材料性能的机械模型和了解各种微结构对先进能源应用的辐射损伤的敏感性非常重要。
