In the present paper, the corrosion fatigue behavior and mechanism of AerMet 100 high-strength steel in a 3.5% NaCl solution was studied by stress-controlled fatigue tests and a series of subsequent characterizations of the fracture surface, microstructure, and cracks. The results indicated that the fatigue life of AerMet 100 high-strength steel decreased with a decrease in the stress level in a 3.5% NaCl solution, satisfying the relationship lgN = \u22122.69 \u00d7 10\u22123 \u03c3 + 6.49. The corrosion fatigue crack usually initiated from the corrosion pit and propagated across the martensitic flat noodles. Meanwhile, the corrosion fatigue crack tip was filled with Cr2O3, Fe2O3, and amorphous material; it propagated in the transgranular mode by a slip dissolution mechanism. This study provides some engineering significant for the fatigue performance of AerMet 100 steel in a 3.5% NaCl solution.<\/jats:p>","DOI":"10.3390\/ma17205025","type":"journal-article","created":{"date-parts":[[2024,10,14]],"date-time":"2024-10-14T12:44:31Z","timestamp":1728909871000},"page":"5025","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The Corrosion Fatigue Behavior and Mechanism of AerMet 100 Steel in 3.5% NaCl at Room Temperature"],"prefix":"10.3390","volume":"17","author":[{"given":"Donghua","family":"Tian","sequence":"first","affiliation":[{"name":"National Center for Materials Service Safety, University of Science and Technology Beijing, Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Can","family":"Xu","sequence":"additional","affiliation":[{"name":"National Center for Materials Service Safety, University of Science and Technology Beijing, Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongli","family":"Wang","sequence":"additional","affiliation":[{"name":"Chengdu Advanced Metal Materials Industrial Technology Institute Co., Ltd., Chengdu 610300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengchuan","family":"Wu","sequence":"additional","affiliation":[{"name":"Chengdu Advanced Metal Materials Industrial Technology Institute Co., Ltd., Chengdu 610300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yonghao","family":"Lu","sequence":"additional","affiliation":[{"name":"National Center for Materials Service Safety, University of Science and Technology Beijing, Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"754","DOI":"10.1007\/s12613-020-2242-6","article-title":"Effect of microstructure on corrosion behavior of high strength martensite steel\u2014A literature review","volume":"28","author":"Wang","year":"2021","journal-title":"Int.
