It was clarified that the threshold of the creep damage that PAUT and ECT・HTS-dc-SQUID could detect appear in later stage of creep deformation. Creep voids were detected on the replica obtained from surface of creep specimens just before creep rupture. Capacitive strain sensor, laser displacement meter and SPICA strain measurement were tried to detect creep strain. Creep curves by the capacitive strain sensor and laser displacement meter were similar with that of conventional extensometer with a linear gauge. Strain measured by SPICA in heat affected zone monotonously increased during creep. Strain measured by capacitive strain sensor, laser displacement meter and SPICA and damage detected by PAUT and ECT・HTS-dc-SQUID were assumed to be useful for residual creep life assessment. description_type: abstract lang: jpn ## Creator - name: 澤田 浩太 role: author orcid: https://orcid.org/0000-0001-7780-1648 organization: 物質・材料研究機構 department: 構造材料研究拠点/構造材料試験プラットフォーム ror: https://ror.org/026v1ze26 - name: 谷内 泰志 role: author orcid: https://orcid.org/0000-0002-9988-3370 organization: 物質・材料研究機構 department: 構造材料研究拠点/構造材料試験プラットフォーム/クリープグループ ror: https://ror.org/026v1ze26 - name: 野島 健大 role: author orcid: https://orcid.org/0000-0002-1307-2770 organization: 物質・材料研究機構 department: 構造材料研究拠点/構造材料試験プラットフォーム/クリープグループ ror: https://ror.org/026v1ze26 - name: 木村 一弘 role: author orcid: https://orcid.org/0000-0001-7906-2703 organization: 物質・材料研究機構 department: 構造材料研究拠点 ror: https://ror.org/026v1ze26 - name: 木村尭弘 role: author organization: 株式会社IHI - name: 野村恭兵 role: author organization: 株式会社IHI - name: 齋藤規子 role: author organization: 株式会社IHI - name: 森田 聡 role: author organization: 関西電力 - name: 早川弘之 role: author organization: 九州電力株式会社 - name: 杉内栄夫 role: author organization: 中国電力 - name: 大櫃和成 role: author organization: 中国電力 - name: 石原潤一 role: author organization: 中国電力 - name: 屋口正次 role: author organization: 電力中央研究所 - name: 西沢孝壽 role: author organization: 東京電力ホールディングス - name: 飯田英男 role: author organization: 東京電力ホールディングス - name: 大井浩二 role: author organization: 東京パワーテクノロジー - name: 西岡智也 role: author organization: 日鉄テクノロジー - name: 江見直哉 role: author organization: 日鉄テクノロジー - name: 岡田浩一 role: author organization: 日鉄テクノロジー - name: 駒井伸好 role: author organization: 三菱重工業 - name: 林 恭平 role: author organization: 三菱重工業 - name: 富永　公彦 role: author organization: 三菱重工業 ## Contact agent ## Publisher organization: 日本材料学会 ## Managing organization ## Keyword - subject: Gr.91 steel welds schema: not_defined - subject: residual creep life schema: not_defined - subject: creep damage detection schema: not_defined - subject: nondestructive method schema: not_defined ## Rights - description: 著作権は公益社団法人日本材料学会（The　Society of Materials Science，Japan）が保有 identifier: http://rightsstatements.org/vocab/InC/1.0/ ## Other identifier(s) ## Data origin - data_origin_type: other ## Embargo ## Journal - title: Zairyo/Journal of the Society of Materials Science, Japan issn: '05145163' volume: '72' issue: '10' start_page: 705 end_page: 712 ## Conference ## Related item ## Funding ## Instrument ## Instrument operator ## Instrument managing organization ## Measurement method ## Specimen ## Chemical composition ## Structure for specimen ## Structural feature for specimen ## Specific property for specimen ## Process for specimen treatment ## Computational method ## Energy level/transition state ## Software ## Custom property ## Fileset - id: 5baf2baa-4ca3-4259-9bbe-623a18e2950b filename: MDR登録用_著者校正前.pdf content_type: application/pdf size: 5233190 md5: a3a724885753328cb737879ca1cadd85 ## Thumbnail fileset_id: 5baf2baa-4ca3-4259-9bbe-623a18e2950b filename: MDR登録用_著者校正前.pdf
