The penetration depth of the welding bead clearly increased even when the sulfur content of the sample was only very slightly increased from 5 to 20 ppm. In situ observation of the surface of the molten pool revealed that the increase in penetration depth of the welding bead could be attributed to an elevation of the average temperature at the center of the molten pool from 2070 to 2200 K due to the generation of an inward fluid flow in the pool. The results of precise measurements of the surface tension of molten high manganese stainless steels using the electromagnetic levitation (EML) technique, thoroughly explained that the inward flow in the molten pool of the sample containing a sulfur content of 20 ppm was induced by Marangoni convection driven by the boomerang shape temperature dependence of the surface tension of the molten sample. The experimental results of the variations in the temperature distribution and the fluid flow direction in the molten pool depending on the sulfur content were reproduced well by a numerical calculation considering the four dominant driving forces of plasma jet, buoyancy, electromagnetic forces, and Marangoni convection, which indicated that the fluid flow direction was dominantly controlled by Marangoni convection.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Nature"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s11661-021-06468-2","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://link.springer.com/article/10.1007/s11661-021-06468-2","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1073-5623","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":"KISAKA,, YUJI"}],"nameIdentifiers":[{"nameIdentifier":"1023408","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SEKIGUCHI, NOBUO"}],"nameIdentifiers":[{"nameIdentifier":"1023409","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tomone, Suwa"}],"nameIdentifiers":[{"nameIdentifier":"1023410","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshikazu, Takahashi"}],"nameIdentifiers":[{"nameIdentifier":"1023411","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tomone, Suwa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1023412","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshikazu, Takahashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1023413","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":"Influence of Sulfur Content on Penetration Depth in TIG Welding for High Manganese Stainless Steels","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Influence of Sulfur Content on Penetration Depth in TIG Welding for High Manganese Stainless Steels"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-10-18"},"publish_date":"2021-10-18","publish_status":"0","recid":"84829","relation_version_is_last":true,"title":["Influence of Sulfur Content on Penetration Depth in TIG Welding for High Manganese Stainless Steels"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:10:19.462545+00:00"}
