The results indicate that the increasing number of rolling passes induces a modified surface layer characterized by refined grains and dislocations, increased hardness, and compressive residual stress (RS). SMRT specimens exhibited improved tensile strength but plasticity performance was decreased. At room temperature (RT) about 25 \u00b0C, the fatigue limit at 1 \u00d7 10 7 cycles of specimens treated with 10 rolling pass was increased from 437 MPa to 613 MPa (40.3%). At 400 \u00b0C, the fatigue limit of specimens treated with 10 passes was increased from 376 MPa to 425 MPa (13.0%) at 400 \u00b0C, but decreased at 650 \u00b0C. The enhanced fatigue performance is attributed to a modified surface layer, leading to the shift of the crack initiation to the subsurface. However, excessive rolling passes and high temperature (650 \u00b0C) significantly reduce the material plasticity, accelerating crack initiation and propagation, thus compromising performance.<\/jats:p>","DOI":"10.3390\/ma19010078","type":"journal-article","created":{"date-parts":[[2025,12,26]],"date-time":"2025-12-26T03:06:02Z","timestamp":1766718362000},"page":"78","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Investigation of Rotary Bending Fatigue Properties of 4Cr14Ni14W2Mo Engine Valve Steel Processed by Surface Mechanical Rolling Treatment"],"prefix":"10.3390","volume":"19","author":[{"given":"Ge","family":"Sun","sequence":"first","affiliation":[{"name":"Huaiji Dengyue Valve Co., Ltd., Zhaoqing 526400, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhifeng","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering and Automation, Fuzhou University, Fuzhou 350116, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zengrui","family":"Yuan","sequence":"additional","affiliation":[{"name":"Weichai Power Co., Ltd., Weifang 261061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rong","family":"Qu","sequence":"additional","affiliation":[{"name":"Huaiji Dengyue Valve Co., Ltd., Zhaoqing 526400, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-0562-6171","authenticated-orcid":false,"given":"Fuqiang","family":"Lai","sequence":"additional","affiliation":[{"name":"Huaiji Dengyue Valve Co., Ltd., Zhaoqing 526400, China"},{"name":"School of Mechanical Engineering and Automation, Fuzhou University, Fuzhou 350116, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Beerens, C., Mueller, A., and Karrip, K.
