According as the contents of Ni and Mn increased, microstructures of the work material were changed roughly in four groups; 1\uff09hypereutectoid steel structure, 2\uff09martensite with retained austenite, 3\uff09austenite and 4\uff09austenite with complex Fe-Mn carbide. Therefore Rockwell hardness number of the work changed within the range of HRB81. 2-HRC49.9. In each combination of the work material and cutting tool, vertical cutting force, i.e. principal force, was measured within the range of cutting speed 7-80m/min by using a dynamometer in a lathe. The principal forces obtained by using P20 were greater than those by K01. In case of using K01, principal force showed between 250-600N, independently of hardness of the work. When using P20, it seemed that the harder material was, the greater principal force was obtained. However, this tendency were discontinuous for the materials having intermediate hardness. On the whole, the relation between principal force and Rockwell hardness was not observed directly. Cutting tool which is suitable for the microstructure of work material and proper cutting speed should be selected to get good surfaces, especially when the microstructure would change according to contents of alloy elements such as Fe-Ni-Mn alloy reported in this paper.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u5de5\u5b66\u90e8"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/13208"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0389-102X"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN0025048X"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u5de5\u5b66\u90e8\u7d00\u8981"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicIssueNumber": "39", "bibliographicPageEnd": "37", "bibliographicPageStart": "27"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "No39p027.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2005035/files/No39p027.pdf"}, "version_id": "9f489be9-e3c8-455f-a56f-e67162537da8"}]}, "item_title": "Fe-Ni-Mn\u5408\u91d1\u306e\u88ab\u524a\u6027", "item_type_id": "15", "owner": "1", "path": ["1642837865010", "1642838406845"], "permalink_uri": "http://hdl.handle.net/20.500.12000/13208", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-11-18"}, "publish_date": "2009-11-18", "publish_status": "0", "recid": "2005035", "relation": {}, "relation_version_is_last": true, "title": ["Fe-Ni-Mn\u5408\u91d1\u306e\u88ab\u524a\u6027"], "weko_shared_id": -1}
