The surface temperature of the W coating increased up to 2000 °C at 15 MW m−2 for 5 s. No severe morphological changes, for example, melting, cracking and delamination were observed although recrystallization and grain growth were found in the W coating. Cyclic loading at 15 MW m−2 for 3 s with 50 cycles and additional 50 cycles with longer pulse length of 4 s produced again no severe morphological changes. Heat transfer analysis of the W-coated CFC sample during the high heat flux test showed that thermal resistance between W coatings and CFCs was negligibly low. This analysis also showed that the surface temperature of the 1 mm thick W coating on the actively cooled CFC monoblock divertor target in JT-60SA will be higher than the recrystallization temperature, 1200 °C, at the steady state heat flux of 15 MW m−2. Therefore, a reduction of armor thickness of the future actively cooled W-coated CFC monoblock divertor target in JT-60SA could be necessary to decrease the surface temperature to less than the recrystallization temperature.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1402-4896/aa8c54/meta","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://iopscience.iop.org/article/10.1088/1402-4896/aa8c54/pdf"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://iopscience.iop.org/article/10.1088/1402-4896/aa8c54/pdf","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0031-8949","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":"福本, 正勝"}],"nameIdentifiers":[{"nameIdentifier":"492238","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Henri, Greuner"}],"nameIdentifiers":[{"nameIdentifier":"492239","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bernd, Boeswirth"}],"nameIdentifiers":[{"nameIdentifier":"492240","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Stefan, Elgeti"}],"nameIdentifiers":[{"nameIdentifier":"492241","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hans, Maier"}],"nameIdentifiers":[{"nameIdentifier":"492242","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Rudolf, Neu"}],"nameIdentifiers":[{"nameIdentifier":"492243","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"仲野, 友英"}],"nameIdentifiers":[{"nameIdentifier":"492244","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"黒木, 信義"}],"nameIdentifiers":[{"nameIdentifier":"492245","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"能見, 健司"}],"nameIdentifiers":[{"nameIdentifier":"492246","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高畠, 剛"}],"nameIdentifiers":[{"nameIdentifier":"492247","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田, 直亮"}],"nameIdentifiers":[{"nameIdentifier":"492248","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福本 正勝","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"492249","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"仲野 友英","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"492250","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"High heat flux testing of mm-thick tungsten coatings on carbon-fiber composites for the JT-60SA tokamak","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High heat flux testing of mm-thick tungsten coatings on carbon-fiber composites for the JT-60SA tokamak"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-05-08"},"publish_date":"2018-05-08","publish_status":"0","recid":"48864","relation_version_is_last":true,"title":["High heat flux testing of mm-thick tungsten coatings on carbon-fiber composites for the JT-60SA tokamak"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:23:30.255653+00:00"}
