However, this process is much energy consumption. On the other hand, lead has been added conventionally in order to improve the machinability of metallic materials. The development of lead-free alloy has become an important issue since lead is harmful to the human body. In this study, MnS was applied to a substitutional material of lead to improve machinability and a direct consolidation process from machined chips of 60/40 brass has been developed. Mixture of machined chips of 60/40 brass and the MnS powder of 0.1-1.0 mass% were consolidated by hot extrusion. Extrusion was conducted at 773 K and an extrusion ratio of 11.1. After the tensile test of the extruded specimen, the tensile strength of the extruded specimen with MnS and that without MnS showed a nearly equivalent value. And tensile strength of the extruded specimen with MnS particles of 106 µm in diameter was slightly higher than that of 45 µm in diameter. Elongation of the extruded specimen decreased with an increase of the MnS additive amount. The cutting resistance test and the chip observation indicated that an increase of MnS additive improved machinability.","subitem_description_type":"Other"}]},"item_9_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"27463","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sato, Naoki"}]},{"nameIdentifiers":[{"nameIdentifier":"27464","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Takeda, Ryosuke"}]},{"nameIdentifiers":[{"nameIdentifier":"27465","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nishimoto, Akio"}]},{"nameIdentifiers":[{"nameIdentifier":"27466","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Maruyama, Toru"}]}]},"item_9_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本銅学会"}]},"item_9_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"本文は日本銅学会の許諾を得て作成しています"}]},"item_9_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11995570","subitem_source_identifier_type":"NCID"}]},"item_9_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13477234","subitem_source_identifier_type":"ISSN"}]},"item_9_text_35":{"attribute_name":"出版者（他言語）","attribute_value_mlt":[{"subitem_text_value":"Japan Institute of Copper"}]},"item_9_version_type_17":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐藤, 直樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"竹田, 諒佑"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"西本, 明生"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"丸山, 徹"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-23"}],"displaytype":"detail","filename":"KU-1100-20140800-01.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KU-1100-20140800-01","url":"https://kansai-u.repo.nii.ac.jp/record/11592/files/KU-1100-20140800-01.pdf"},"version_id":"b3bf5447-364f-4d3d-8f3c-51d8fc589110"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"黄銅","subitem_subject_scheme":"Other"},{"subitem_subject":"切削屑","subitem_subject_scheme":"Other"},{"subitem_subject":"熱間押出し","subitem_subject_scheme":"Other"},{"subitem_subject":"快削黄銅","subitem_subject_scheme":"Other"},{"subitem_subject":"硫化マンガン","subitem_subject_scheme":"Other"},{"subitem_subject":"鉛フリー銅合金","subitem_subject_scheme":"Other"},{"subitem_subject":"60/40 brass","subitem_subject_scheme":"Other"},{"subitem_subject":"machined chips","subitem_subject_scheme":"Other"},{"subitem_subject":"hot extrusion","subitem_subject_scheme":"Other"},{"subitem_subject":"machinable brass","subitem_subject_scheme":"Other"},{"subitem_subject":"manganese sulfide","subitem_subject_scheme":"Other"},{"subitem_subject":"lead-free copper alloy","subitem_subject_scheme":"Other"},{"subitem_subject":"brass","subitem_subject_scheme":"Other"},{"subitem_subject":"関西大学","subitem_subject_scheme":"Other"},{"subitem_subject":"Kansai University","subitem_subject_scheme":"Other"}]},"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":"熱間押出し法による黄銅切削屑からの硫化マンガン分散鉛フリー快削黄銅の調製","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"熱間押出し法による黄銅切削屑からの硫化マンガン分散鉛フリー快削黄銅の調製"}]},"item_type_id":"9","owner":"1","path":["1597"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-11-09"},"publish_date":"2016-11-09","publish_status":"0","recid":"11592","relation_version_is_last":true,"title":["熱間押出し法による黄銅切削屑からの硫化マンガン分散鉛フリー快削黄銅の調製"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-05-15T13:36:57.265588+00:00"}
