Outline of Final Research Achievements

The structural materials used in nuclear power plants are exposed to not only high temperature but also harsh radiation environments. Therefore, in addition to high temperature stability, excellent irradiation resistance is required for nuclear materials. In the present study, nanostructured SiC thin films with a large amount of surface defects were fabricated, and their structural changes upon irradiation were investigated using ion beam techniques and transmission electron microscopy. As a result, it was found that the irradiation resistance of nanostructured SiC was better than that of single-crystalline SiC under heavy-ion irradiation as the irradiation energy increased.

Academic Significance and Societal Importance of the Research Achievements

本研究では優れた耐照射性を有する材料の開発を目的として、炭化ケイ素(SiC)に多量の面欠陥を導入した「ナノ構造SiC」の照射挙動を、イオンビーム技術と透過電子顕微鏡法により調査した。SiC中の面欠陥は1000℃以上の高温環境下でも安定に存在し、実操業条件においても組織変化による材料劣化を抑制できると考えられる。優れた耐照射性材料の開発は、原子力産業分野に使用される構造材料の信頼性に寄与することが期待される。
