We examined the pressure behavior of a mold cavity in one chamber titanium casting system operated with helium and argon gas. The increasing pressure rate at the beginning of the casting depended on both the gas type and gas permeability characteristics of the mold. The maximum of the difference pressure corresponding to the driving force for casting was similar under the same molds suitable for the pressure casting system regardless of gas type. Meanwhile, after the casting pressure reached the maximum, the pressure quickly decreased, and in some cases, the decreasing rate of the pressure with helium gas was higher than that of the pressure with argon gas. Accordingly, the argon gas was suitable for the one chamber titanium casting system. That was because the higher casting pressure was applied to the mold cavity for a long time. The behavior of casting pressure depending on both the gas type and the gas permeability characteristic of mold might have a strong influence on the formation of casting defects.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "149609", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Okawa, Seigo"}]}, {"nameIdentifiers": [{"nameIdentifier": "149610", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Watanabe, Kouichi"}]}, {"nameIdentifiers": [{"nameIdentifier": "149611", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kanatani, Mitsugu"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟歯学会"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN0018300X", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03850153", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "大川, 成剛"}], "nameIdentifiers": [{"nameIdentifier": "149606", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "渡辺, 孝一"}], "nameIdentifiers": [{"nameIdentifier": "149607", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "金谷, 貢"}], "nameIdentifiers": [{"nameIdentifier": "149608", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-19"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "NS_42(2)_97-102.pdf", "filesize": [{"value": "1.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1400000.0, "url": {"label": "NS_42(2)_97-102.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/25392/files/NS_42(2)_97-102.pdf"}, "version_id": "90d205db-3a4e-40a6-84b3-6a250d0379fa"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "一室加圧型鋳造", "subitem_subject_scheme": "Other"}, {"subitem_subject": "通気性", "subitem_subject_scheme": "Other"}, {"subitem_subject": "鋳造ガス", "subitem_subject_scheme": "Other"}, {"subitem_subject": "鋳型", "subitem_subject_scheme": "Other"}, {"subitem_subject": "鋳造圧", "subitem_subject_scheme": "Other"}, {"subitem_subject": "one chamber casting system", "subitem_subject_scheme": "Other"}, {"subitem_subject": "permeability", "subitem_subject_scheme": "Other"}, {"subitem_subject": "casting gas", "subitem_subject_scheme": "Other"}, {"subitem_subject": "mold", "subitem_subject_scheme": "Other"}, {"subitem_subject": "casting pressure", "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "ヘリウムガスを用いた一室加圧型鋳造における鋳型空洞の圧力挙動", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "ヘリウムガスを用いた一室加圧型鋳造における鋳型空洞の圧力挙動"}, {"subitem_title": "ヘリウムガスを用いた一室加圧型鋳造における鋳型空洞の圧力挙動", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1293"], "permalink_uri": "http://hdl.handle.net/10191/50511", "pubdate": {"attribute_name": "公開日", "attribute_value": "2018-08-30"}, "publish_date": "2018-08-30", "publish_status": "0", "recid": "25392", "relation": {}, "relation_version_is_last": true, "title": ["ヘリウムガスを用いた一室加圧型鋳造における鋳型空洞の圧力挙動"], "weko_shared_id": null}
