    摘要:

    铀及铀合金是核工业中重要的结构和功能材料,其腐蚀状态对于材料的使役有效性有重要影响。材料学因素,包括组分、组织结构、内部和表面的缺陷状态等是影响铀材料耐蚀性能的内因。本文重点综述了铀材料中微缺陷对腐蚀的影响规律的研究现状,从杂质元素、夹杂、显微组织、表面状态四个方面系统梳理了国内外公开报道的研究工作和取得的规律认识。在此基础上,简要的提出了改善和消除微缺陷以提升铀材料耐蚀性能的策略。

    Abstract:

    Uranium metal and its alloys played important roles in the files of nuclear industry, working as configurational or functional materials. The corrosion behavior of them attracted people"s interest because it would greatly affect the materials" performance. Material factors, including components, microstructures, defects in body and on the surface, were the internal causes to affect the corrosion resistance of uranium materials. This paper conducted a review on how the defects of uranium materials affected their corrosion behavior. We summarized the reported works from four aspects: impurity, inclusions, microstructures and surface states. Strategies to improve the corrosion resistance of uranium materials by means of modulating these defects were also briefly discussed.
