Neutron irradiation of titanium beryllide together with beryllium as a reference material in material testing nuclear reactors can give essential data for the DEMO blanket design. Be-7at.%Ti (Be-7Ti) as well as Be were irradiated in the HFR, Petten, the Netherlands, at four temperatures of 710, 800, 940, 1040 K up to 23, 31, 36, 38 dpa, respectively. The post-irradiation examination (PIE) included thermal-programmed desorption (TPD) and Vickers hardness tests as well as microstructure study by optical metallography. Be and Be-7Ti pellets maintained their integrity after irradiation. Microstructure of Be-7Ti contains two phases, mainly, TiBe12, and also small amount of Be. Under irradiation, gas bubbles were formed in Be samples as well as in Be-phase in Be-7Ti samples. These bubbles contain helium and tritium produced in Be under irradiation. TPD tests showed a much lower tritium retention in Be-7Ti than in Be for all four irradiation temperatures. Vickers hardness of TiBe12 phase is much higher than that of Be-phase. According to the obtained data, Be-7Ti could be considered more preferred than Be as a neutron multiplier material in future fusion reactors due to the enhanced radiation damage resistance.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.fusengdes.2020.111938","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/pii/S0920379620304865","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0920-3796","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":"Chakin, Vladimir"}],"nameIdentifiers":[{"nameIdentifier":"1008776","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Rolli, Rolf"}],"nameIdentifiers":[{"nameIdentifier":"1008777","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Gaisin, Ramil"}],"nameIdentifiers":[{"nameIdentifier":"1008778","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ursula, Hoeppener-Kramar"}],"nameIdentifiers":[{"nameIdentifier":"1008779","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakamichi, Masaru"}],"nameIdentifiers":[{"nameIdentifier":"1008780","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zmitko, Milan"}],"nameIdentifiers":[{"nameIdentifier":"1008781","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masaru, Nakamichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1008782","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":"Tritium release and retention in beryllium and titanium beryllide after neutron irradiation up to damage doses of 23-38 dpa","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Tritium release and retention in beryllium and titanium beryllide after neutron irradiation up to damage doses of 23-38 dpa"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-03-09"},"publish_date":"2021-03-09","publish_status":"0","recid":"82079","relation_version_is_last":true,"title":["Tritium release and retention in beryllium and titanium beryllide after neutron irradiation up to damage doses of 23-38 dpa"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:11:01.923676+00:00"}
