To the best of our knowledge, this study presents the first experimental evidence of radiation-enhanced recrystallization in W and undoped W–Re alloys at ~850 °C, conditions where thermal annealing does not cause any grain growth in a similar timescale. Potassium- or lanthanum-doped tungsten alloys showed more resistance to radiation-enhanced grain growth. We explain the acceleration of grain growth by analyzing the self-diffusion constant under atomic displacement environments. The microstructural observations of the studied W variants suggest that La doping is more effective than K doping for mitigating recrystallization. This study also found that radiation-enhanced crystallization is an important consideration when designing and applying W to plasma-facing components in future nuclear fusion reactors.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.jallcom.2021.163419","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/abs/pii/S0925838821048295?via%3Dihub","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0925-8388","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Gietl, Hanns"}],"nameIdentifiers":[{"nameIdentifier":"1020173","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koyanagi, Takaaki"}],"nameIdentifiers":[{"nameIdentifier":"1020174","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hu, Xunxiang"}],"nameIdentifiers":[{"nameIdentifier":"1020175","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukuda, Makoto"}],"nameIdentifiers":[{"nameIdentifier":"1020176","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hasegawa, Akira"}],"nameIdentifiers":[{"nameIdentifier":"1020177","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Katoh, Yutai"}],"nameIdentifiers":[{"nameIdentifier":"1020178","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Makoto, Fukuda","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1020179","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Neutron irradiation-enhanced grain growth in tungsten and tungsten alloys","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Neutron irradiation-enhanced grain growth in tungsten and tungsten alloys"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-01-07"},"publish_date":"2022-01-07","publish_status":"0","recid":"84518","relation_version_is_last":true,"title":["Neutron irradiation-enhanced grain growth in tungsten and tungsten alloys"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:22:28.881047+00:00"}
