It was found that the gauge length change behaviors of the material are related to (i) the positive damage of the thin interlayer and (ii) to the negative damage of the C phase. The most serious damage of TI C\/SiC under 60 \u00b1 20 MPa occurs in an oxygen partial pressure of 17,000 Pa at 1300 \u00b0C. When the oxygen partial pressure and\/or the temperature are reduced, the positive C phase damage is relieved. In the case that the oxygen partial pressure, temperature and stress increase, the negative C phase damage is facilitated. The oxidation mechanism of the C phase is controlled by the inward diffusion of oxygen from the sample surface to the center; however, a higher stress is considered to change the oxygen diffusion mechanism by increasing the reaction of the C phase, with oxygen causing a widening of microcracks.<\/jats:p>","DOI":"10.3390\/ma17194925","type":"journal-article","created":{"date-parts":[[2024,10,9]],"date-time":"2024-10-09T07:39:52Z","timestamp":1728459592000},"page":"4925","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["High-Temperature Fatigue Degradation Behaviors of a 3D Braided C\/SiC with a Thin Interlayer in Different Dry Oxygen Atmospheres"],"prefix":"10.3390","volume":"17","author":[{"given":"Lexin","family":"Yang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Clean and Efficient Turbomachinery Power Equipment, Deyang 618000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dianwei","family":"He","sequence":"additional","affiliation":[{"name":"Science and Technology on Thermostructural Composite Materials Laboratory, School of Materials Science and Engineering, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Hu","sequence":"additional","affiliation":[{"name":"Science and Technology on Thermostructural Composite Materials Laboratory, School of Materials Science and Engineering, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenhuan","family":"Gao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Clean and Efficient Turbomachinery Power Equipment, Deyang 618000, China"},{"name":"Dongfang Electric Corporation Dongfang Turbine Co., Ltd., Deyang 618000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liping","family":"Nie","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Clean and Efficient Turbomachinery Power Equipment, Deyang 618000, China"},{"name":"Dongfang Electric Corporation Dongfang Turbine Co., Ltd., Deyang 618000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youbei","family":"Sun","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Clean and Efficient Turbomachinery Power Equipment, Deyang 618000, China"},{"name":"Dongfang Electric Corporation Dongfang Turbine Co., Ltd., Deyang 618000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Hangzhou Dianzi University, Hangzhou 310018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingang","family":"Luan","sequence":"additional","affiliation":[{"name":"Science and Technology on Thermostructural Composite Materials Laboratory, School of Materials Science and Engineering, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"652","DOI":"10.3390\/ceramics7020043","article-title":"Ceramic Matrix Composites: Classifications, Manufacturing, Properties, and Applications","volume":"7","author":"Shrivastava","year":"2024","journal-title":"Ceramics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"804","DOI":"10.1038\/nmat4687","article-title":"Advanced structural ceramics in aerospace propulsion","volume":"15","author":"Padture","year":"2016","journal-title":"Nat.
