The cutting performances were summarized based on the assist gas flow rate and the front kerf width, and the range for appropriate cutting conditions was shown. Gas pressure in the kerf region required for molten metal removal was estimated from the pressure loss on the kerf surface, which depended on the gas flow rate and the kerf width. The relation to keep sufficient gas pressure in the kerf well corresponded to the experimental relations for appropriate cutting. Drag force to the typical molten metal structures on the kerf surface was also estimated, which varied by the structures and materials. The behaviors such as cavity formation and its expansion in the kerf region at the unsuccessful cutting trials were well explained. The results are informative for the development of the laser cutting technology applied to the thick steel specimen for the nuclear decommissioning.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Tayler Francis"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1080/00223131.2017.1344156 ","subitem_relation_type_select":"DOI"}}]},"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":"Tamura, Koji"}],"nameIdentifiers":[{"nameIdentifier":"485064","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shin’ichi, Toyama"}],"nameIdentifiers":[{"nameIdentifier":"485065","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田村 浩司","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485066","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":"Laser cutting performances for thick steel specimens studied by molten metal removal conditions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Laser cutting performances for thick steel specimens studied by molten metal removal conditions"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-08-03"},"publish_date":"2017-08-03","publish_status":"0","recid":"48262","relation_version_is_last":true,"title":["Laser cutting performances for thick steel specimens studied by molten metal removal conditions"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:30:07.297347+00:00"}
