The influence of cold swaging on the martensitic transformations in Ti-xMo-2Fe (x = 3.4, 5, 9.2 wt.%) alloys was investigated. In these alloys, appropriate chemical compositions promote a stress-induced phase transformation from the \u03b2 phase to orthorhombic \u03b1\u2033 martensite, which improves elongation while maintaining high strength. As the Mo content increases from 3.4 to 5 wt.%, the amount of \u03b2-stabilizing elements increases and the \u03b2 stability is enhanced, thereby altering the phase transformation mechanism. In the Ti-9.2Mo-2Fe alloy, both \u03b1\u2033 martensite and a very hard \u03c9 phase were identified by X-ray diffraction and transmission electron microscopy. The hard and brittle \u03c9 phase causes premature brittle fracture prior to macroscopic yielding. Among the investigated alloys, the Ti-5Mo-2Fe alloy exhibits the best overall combination of high tensile strength, elongation to failure, and high fatigue strength.<\/jats:p>","DOI":"10.3390\/ma19010010","type":"journal-article","created":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T07:01:33Z","timestamp":1766386893000},"page":"10","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Effect of Molybdenum on Microstructural Evolution and High Cycle Fatigue Properties of Ti-xMo-2Fe Alloys"],"prefix":"10.3390","volume":"19","author":[{"given":"HyoWoon","family":"Hwang","sequence":"first","affiliation":[{"name":"Ceramic Materials R&D Center, OSSTEM IMPLANT Co., Ltd., Seoul 07789, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong-Geun","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Metallurgical Engineering, Sunchon National University, Suncheon 57922, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1504\/IJNBM.2007.016517","article-title":"Review: Titanium and titanium alloy applications in medicine","volume":"1","author":"Balazic","year":"2007","journal-title":"Int.
