The \u03b1\/\u03b2 interface layer was observed in forged and different annealed Ti80 alloys, which is mainly composed of lamellar face-centered cubic (FCC) phase region and \u03b1\u2032 + \u03b2 region.

The influence of element addition on the formation mechanism of the FCC phase was discussed. The addition of Zr promotes the formation of the FCC phase by inducing lattice distortion and reducing the stacking fault energy of the \u03b1 phase. In addition, the Al element forms an obvious concentration gradient around the interface layer during the cooling process of the alloy, which provides a driving force for the formation of the FCC phase.\n                  <\/jats:p>","DOI":"10.1515\/ntrev-2021-0085","type":"journal-article","created":{"date-parts":[[2021,9,16]],"date-time":"2021-09-16T16:25:06Z","timestamp":1631809506000},"page":"1197-1207","source":"Crossref","is-referenced-by-count":12,"title":["Structural characterization and nanoscale strain field analysis of \u03b1\/\u03b2 interface layer of a near \u03b1 titanium alloy"],"prefix":"10.1515","volume":"10","author":[{"given":"Longlong","family":"Lu","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering, Henan University of Science and Technology , Luoyang 471023 , China"},{"name":"Provincial and Ministerial Co-construction Collaborative Innovation Center of Nonferrous New Materials and Advanced Processing Technology , Luoyang 471023 , China"},{"name":"Henan Province Key Laboratory of Nonferrous Materials Science and Processing Technology , Luoyang 471023 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanmin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Henan University of Science and Technology , Luoyang 471023 , China"},{"name":"Provincial and Ministerial Co-construction Collaborative Innovation Center of Nonferrous New Materials and Advanced Processing Technology , Luoyang 471023 , China"},{"name":"Henan Province Key Laboratory of Nonferrous Materials Science and Processing Technology , Luoyang 471023 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kexing","family":"Song","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Henan University of Science and Technology , Luoyang 471023 , China"},{"name":"Provincial and Ministerial Co-construction Collaborative Innovation Center of Nonferrous New Materials and Advanced Processing Technology , Luoyang 471023 , China"},{"name":"Henan Province Key Laboratory of Nonferrous Materials Science and Processing Technology , Luoyang 471023 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiuhua","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Henan University of Science and Technology , Luoyang 471023 , China"},{"name":"Provincial and Ministerial Co-construction Collaborative Innovation Center of Nonferrous New Materials and Advanced Processing Technology , Luoyang 471023 , China"},{"name":"Henan Province Key Laboratory of Nonferrous Materials Science and Processing Technology , Luoyang 471023 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Li","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Henan University of Science and Technology , Luoyang 471023 , China"},{"name":"Provincial and Ministerial Co-construction Collaborative Innovation Center of Nonferrous New Materials and Advanced Processing Technology , Luoyang 471023 , China"},{"name":"Henan Province Key Laboratory of Nonferrous Materials Science and Processing Technology , Luoyang 471023 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shangguang","family":"Li","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Henan University of Science and Technology , Luoyang 471023 , China"},{"name":"Provincial and Ministerial Co-construction Collaborative Innovation Center of Nonferrous New Materials and Advanced Processing Technology , Luoyang 471023 , China"},{"name":"Henan Province Key Laboratory of Nonferrous Materials Science and Processing Technology , Luoyang 471023 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fei","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Henan University of Science and Technology , Luoyang 471023 , China"},{"name":"Provincial and Ministerial Co-construction Collaborative Innovation Center of Nonferrous New Materials and Advanced Processing Technology , Luoyang 471023 , China"},{"name":"Henan Province Key Laboratory of Nonferrous Materials Science and Processing Technology , Luoyang 471023 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"374","published-online":{"date-parts":[[2021,9,16]]},"reference":[{"key":"2025120319344444612_j_ntrev-2021-0085_ref_001","doi-asserted-by":"crossref","unstructured":"Zhang ZX, Fan JK, Tang B, Kou HC, Wang J, Wang X, et al.
