In particular, its high-temperature strength can enhance the safety of electronic products and cars. SDSS AISI2507, known for its excellent strength and high corrosion resistance, was analyzed for its microstructure and electrochemical behavior at the ignition temperature of Li-ion batteries, 700 \u00b0C. At 700 \u00b0C, AISI2507 exhibited secondary phase precipitation values of 1% and 8% after 5 and 10 h, respectively. Secondary phase precipitation was initiated by the expansion of austenite, forming sigma, chi, and CrN phases. The electrochemical behavior varied with the fraction of secondary phases. Secondary phase precipitation reduced the potential (From \u22120.25 V to \u22120.31 V) and increased the current density (From 8 \u00d7 10\u22126 A\/cm2 to 3 \u00d7 10\u22126 A\/cm2) owing to galvanic corrosion by sigma and chi. As the fraction of secondary phases increased (From 0.0% to 8.1%), the open circuit potential decreased (From \u22120.25 V to \u22120.32 V). Secondary phase precipitation is a crucial factor in reducing the corrosion resistance of SDSS AISI2507 and occurs after 1 h of exposure at 700 \u00b0C.<\/jats:p>","DOI":"10.3390\/ma17092009","type":"journal-article","created":{"date-parts":[[2024,4,26]],"date-time":"2024-04-26T03:23:47Z","timestamp":1714101827000},"page":"2009","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Study of Precipitated Secondary Phase at 700 \u00b0C on the Electrochemical Properties of Super Duplex Stainless Steel AISI2507: Advanced High-Temperature Safety of a Lithium-Ion Battery Case"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9662-1156","authenticated-orcid":false,"given":"Byung-Hyun","family":"Shin","sequence":"first","affiliation":[{"name":"Busan Center, Korea Basic Science Institute, Busan 46742, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seongjun","family":"Kim","sequence":"additional","affiliation":[{"name":"Busan Center, Korea Basic Science Institute, Busan 46742, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinyong","family":"Park","sequence":"additional","affiliation":[{"name":"Busan Center, Korea Basic Science Institute, Busan 46742, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jung-Woo","family":"Ok","sequence":"additional","affiliation":[{"name":"Busan Center, Korea Basic Science Institute, Busan 46742, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-5832-7468","authenticated-orcid":false,"given":"Dohyung","family":"Kim","sequence":"additional","affiliation":[{"name":"Innovative Graduate Education Program for Global High-Tech Materials and Parts, Pusan National University, Busan 46241, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8494-9373","authenticated-orcid":false,"given":"Jang-Hee","family":"Yoon","sequence":"additional","affiliation":[{"name":"Busan Center, Korea Basic Science Institute, Busan 46742, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"158024","DOI":"10.1016\/j.apsusc.2023.158024","article-title":"A DFT Study of TiC3 as Anode Material for Li-Ion Batteries","volume":"638","author":"Park","year":"2023","journal-title":"Appl.
