The phenomenon becomes a serious problem for bended section of pneumatic transportation pipe, valve, turbine blade and fun, and so on. In order to reach an aim of high safety and low cost, it’s important to develop wear resistant material and to estimate of life service during erosion. Recently, many researches have studied on the variety of alloys, and tempt to develop wear resistant materials. In this study, the multi-component cast irons, which are excellent war resistant materials due to containing strong carbides forming elements, Crystallization of hard eutectic carbides at the solidification and occurring secondary hardening in matrix by heat treatment was paid attention. Therefore, multi-component cast irons with about 3%C, 10%, 7.5% and 5%V cast irons with nill, 5 and 9%Cr and 2%C and Cr, Mo, W and V, (As an alternative to Nb) of about 5% with 0, 5 and 10%Co were prepared as the test materials in this study. This study investigates erosive wear characteristics of multi-component cast irons. In 1st chapter, I described the research background, previous research and the purpose and significance of this study. In 2nd chapter I melted the variety of multi-component cast irons and subsequent identification of the eutectic carbides, precipitated carbides and matrix. In 3rd chapter, I described that I used the Fe-C-Mn-Cr-V-based multi-component cast irons were melted in the second chapter as specimens, promoting the erosive wear test, to reduce of V contents and increasing of Cr contents were investigated whether it’s possible to increasing wear resistance and cost reduction. In 4th chapter, I used the Fe-C-Cr-Mo-W based multi-component cast irons were melted in the 2nd chapter as test materials, I investigates erosive wear characteristics of Fe-C-Cr-Mo-W multi-component cast irons containing V, Nb and Co. In 5th chapter, we used the Fe-C-Cr-Mo-W-based multi-component cast irons, which showed excellent wear resistance in Chapter IV. To promote a high temperature erosion wear test, I revealed that effect of Co addition on high temperature erosive wear characteristics of multi-component cast irons containing Nb or V. In 6th chapter, summarize results of the present research.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_81_dissertation_number_13":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第373号"}]},"item_81_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15118/00005129","subitem_identifier_reg_type":"JaLC"}]},"item_81_link_5":{"attribute_name":"室蘭工業大学研究者データベースへのリンク","attribute_value_mlt":[{"subitem_link_text":"楠本 賢太（KUSUMOTO Kenta）","subitem_link_url":"http://rdsoran.muroran-it.ac.jp/html/100000201_ja.html"}]},"item_81_subject_9":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"566","subitem_subject_scheme":"NDC"}]},"item_81_text_12":{"attribute_name":"学位の種別","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"課程博士"}]},"item_81_text_14":{"attribute_name":"報告番号","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"甲第373号"}]},"item_81_text_15":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"博甲第373号"}]},"item_81_version_type_24":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{}],"affiliationNames":[{},{}]}],"creatorNames":[{"creatorName":"楠本,  賢太","creatorNameLang":"ja"},{"creatorName":"クスモト, ケンタ","creatorNameLang":"ja-Kana"},{"creatorName":"KUSUMOTO, Kenta","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-15"}],"displaytype":"detail","filename":"A373.pdf","filesize":[{"value":"5.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A373","objectType":"fulltext","url":"https://muroran-it.repo.nii.ac.jp/record/5138/files/A373.pdf"},"version_id":"ac84227c-7462-4162-892c-d5d9f8307853"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-15"}],"displaytype":"detail","filename":"A373_summary.pdf","filesize":[{"value":"471.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A373_summary","objectType":"abstract","url":"https://muroran-it.repo.nii.ac.jp/record/5138/files/A373_summary.pdf"},"version_id":"7bc81364-b1ad-4224-889b-fa2b318212c8"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"多合金鋳鉄のエロージョン磨耗特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"多合金鋳鉄のエロージョン磨耗特性","subitem_title_language":"ja"}]},"item_type_id":"81","owner":"18","path":["227","226"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-11"},"publish_date":"2015-06-11","publish_status":"0","recid":"5138","relation_version_is_last":true,"title":["多合金鋳鉄のエロージョン磨耗特性"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-10-23T02:09:16.394471+00:00"}
