For dhcp-FeHx, slight reduction in volume starting at around 500 K on heating was observed in the V–T relations. This is likely related to magnetic transition.  For fcc-FeHx, the expanded volumes per Fe atom with respect to fcc-Fe metal were converted to hydrogen compositions x using hydrogen-induced volume pansion vH. A miscibility ｇap in the x–T diagram of fcc-FeHx was confirmed to be in agreement with an earlier study, and the critical pressure was located in a rather narrow span of 4.0–4.5 GPa with a critical composition of x = ~0.4. We xamined Arrhenius plot analysis of the x–T relations to derive the enthalpy of  solution of hydrogen delta-Hs. However, an irregular behavior of the x–T relations did not allow  derivation of a reliable value of delta-Hs.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.jallcom.2017.02.209","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.sciencedirect.com/science/article/pii/S0925838817306552"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.sciencedirect.com/science/article/pii/S0925838817306552","subitem_relation_type_select":"URI"}}]},"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":"齋藤, 寛之"}],"nameIdentifiers":[{"nameIdentifier":"481501","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"町田, 晃彦"}],"nameIdentifiers":[{"nameIdentifier":"481502","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sugimoto, Hidehiko"}],"nameIdentifiers":[{"nameIdentifier":"481503","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yagi, Takehiko"}],"nameIdentifiers":[{"nameIdentifier":"481504","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"青木, 勝敏"}],"nameIdentifiers":[{"nameIdentifier":"481505","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"齋藤 寛之","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"481506","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"町田 晃彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"481507","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"青木 勝敏","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"481508","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":"P-V-T relation of the Fe-H system under hydrogen pressure of several gigapascals","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"P-V-T relation of the Fe-H system under hydrogen pressure of several gigapascals"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-05-23"},"publish_date":"2017-05-23","publish_status":"0","recid":"47962","relation_version_is_last":true,"title":["P-V-T relation of the Fe-H system under hydrogen pressure of several gigapascals"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:33:34.785696+00:00"}
