Glassy carbon, a monoatomic allotrope of carbon, is a candidate material for components in fission nuclear power systems due to its radiation tolerance. This article presents comprehensive electron microscopy data revealing the effects of neutron and electron irradiation on glassy carbon. For comparison, additional data are provided for pyrolytic graphite and carbon fibers, materials that exhibit similar structural behavior under irradiation. electron irradiation experiments further illustrate the real-time microstructural evolution of glassy carbon during exposure. The dataset is organized into five parts: (1) transmission electron microscopy (TEM) micrographs of as-received and neutron-irradiated glassy carbon; (2) TEM micrographs of neutron-irradiated graphite; (3) TEM micrographs of unirradiated and irradiated carbon-carbon composites; (4) TEM micrographs of pyrolytic carbon specimens in both conditions; (5) scanning transmission electron microscopy (STEM) micrographs of as-received and neutron-irradiated glassy carbon and (6) electron irradiation data of a glassy carbon particle. These datasets provide valuable insights into radiation-induced structural changes in carbon-based materials relevant to nuclear applications.
玻璃碳是碳的一种单原子同素异形体,由于其耐辐射性,是裂变核电系统中部件的候选材料。本文展示了全面的电子显微镜数据,揭示了中子和电子辐照对玻璃碳的影响。为作比较,还提供了热解石墨和碳纤维在辐照下表现出类似结构行为的材料的额外数据。电子辐照实验进一步阐明了玻璃碳在辐照过程中的实时微观结构演变。数据集分为五个部分:(1)未辐照和经中子辐照的玻璃碳的透射电子显微镜(TEM)显微照片;(2)经中子辐照的石墨的TEM显微照片;(3)未辐照和辐照后的碳 - 碳复合材料的TEM显微照片;(4)两种条件下热解碳试样的TEM显微照片;(5)未辐照和经中子辐照的玻璃碳的扫描透射电子显微镜(STEM)显微照片;以及(6)玻璃碳颗粒的电子辐照数据。这些数据集为与核应用相关的碳基材料中辐射诱导的结构变化提供了有价值的见解。
