Creep strain measurements were also performed for residual life assessment of the welds. PAUT showed that the threshold of creep damage detection was between 60% and 80% of the creep life. In the case of ECT• HTS-dc-SQUID, the threshold was between 80% and 90% of the creep life. Creep voids were observed on the replica just before creep rupture. A capacitive strain sensor, laser displacement meter, and SPICA strain measurement were used to detect changes in the strain during creep exposure. The capacitive strain sensor can continuously measure the strain during creep exposure. The laser displacement meter was used after creep interruption. Creep curves obtained by the capacitive strain sensor and laser displacement meter w description_type: abstract lang: eng ## Creator - name: Kota Sawada role: author orcid: https://orcid.org/0000-0001-7780-1648 organization: National Institute for Materials Science department: Research Center for Structural Materials/Materials Evaluation Field/Creep Property Group ror: https://ror.org/026v1ze26 - name: Yasushi Taniuchi role: author orcid: https://orcid.org/0000-0002-9988-3370 organization: National Institute for Materials Science department: Research Network and Facility Services Division/Materials Data Platform/Creep Data Unit ror: https://ror.org/026v1ze26 - name: Takehiro Nojima role: author orcid: https://orcid.org/0000-0002-1307-2770 organization: National Institute for Materials Science department: Research Network and Facility Services Division/Materials Data Platform/Creep Data Unit ror: https://ror.org/026v1ze26 - name: Kazuhiro Kimura role: author orcid: https://orcid.org/0000-0001-7906-2703 organization: National Institute for Materials Science department: Research Center for Structural Materials ror: https://ror.org/026v1ze26 - name: Takahiro Kimura role: author organization: IHI Corporation - name: Kyohei Nomura role: author organization: IHI Corporation - name: Noriko Saito role: author organization: IHI Corporation - name: Akira Morita role: author organization: The Kansai Electric Power - name: Hiroyuki Hayakawa role: author organization: Kyushu Electric Power Co., Inc. - name: Takao Sugiuchi role: author organization: The Chugoku Electric Power - name: Kazushige Ohbitsu role: author organization: The Chugoku Electric Power - name: Masatsugu Yaguchi role: author organization: Central Research Institute of Electric Power Industry (CRIEPI)/電力中央研究所 - name: Koju Nishizawa role: author organization: Tokyo Electric Power Company Holdings - name: Hiroshi Ozaki role: author organization: Tokyo Electric Power Company Holdings - name: Hayato Fukunishi role: author organization: Tokyo Electric Power Company Holdings - name: Kouji Ohi role: author organization: Tokyo Power Technology - name: Tomoya Nishioka role: author organization: Nippon Steel Technology - name: Naoya Emi role: author organization: Nippon Steel Technology - name: Hirokazu Okada role: author organization: Nippon Steel Technology - name: Nobuyoshi Komai role: author organization: Mitsubishi Heavy Industries, Ltd. - name: Kyohei Hayashi role: author organization: Mitsubishi Heavy Industries, Ltd. - name: Kimihiko Tominaga role: author organization: Mitsubishi Heavy Industries, Ltd. ## Contact agent ## Publisher organization: ASM International ## Managing organization ## Keyword - subject: Gr.91 steel welds, creep, damage, nondestructive evaluation schema: not_defined ## Rights - description: Copyright © 2024 ASM International.
