In the S-EM, the thin \u03b2 lamellae grow through the equiaxed \u03b1p phase (\u03b1p), and the original \u03b1p\/\u03b2trans interface in the bimodal microstructure largely disappears, forming a blurry interface between the semi-equiaxed \u03b1p phase (equiaxed \u03b1p phase that is grew through by the thin \u03b2 lamellae) and the transformed \u03b2 microstructure (\u03b2trans). The formation of dense slip bands inside the semi-equiaxed \u03b1p phase in the S-EM is inhibited by the thin \u03b2 lamellae during the tensile deformation. The special characteristics of the S-EM reduce the stress concentration at the interface, and the crack initiation probability in the blurry semi-\u03b1p\/\u03b2trans interface decreased compared to the distinct \u03b1p\/\u03b2trans interface in a conventional equiaxed microstructure (EM). Moreover, the ultimate tensile strength of the S-EM is higher than that of the EM with a slight loss of plasticity.<\/jats:p>","DOI":"10.3390\/ma14123380","type":"journal-article","created":{"date-parts":[[2021,6,18]],"date-time":"2021-06-18T11:19:20Z","timestamp":1624015160000},"page":"3380","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Deformation Behavior and Tensile Properties of the Semi-Equiaxed Microstructure in Near Alpha Titanium Alloy"],"prefix":"10.3390","volume":"14","author":[{"given":"Minglang","family":"Luo","sequence":"first","affiliation":[{"name":"College of Materials and Metallurgy, Guizhou University, Guiyang 550025, China"},{"name":"Guizhou Key Laboratory for Mechanical Behavior and Microstructure of Materials, Guizhou University, Guiyang 550025, China"},{"name":"National & Local Joint Engineering Laboratory for High-Performance Metal Structure Material and Advanced Manufacturing Technology, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tingyi","family":"Lin","sequence":"additional","affiliation":[{"name":"College of Materials and Metallurgy, Guizhou University, Guiyang 550025, China"},{"name":"Guizhou Key Laboratory for Mechanical Behavior and Microstructure of Materials, Guizhou University, Guiyang 550025, China"},{"name":"National & Local Joint Engineering Laboratory for High-Performance Metal Structure Material and Advanced Manufacturing Technology, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Materials and Metallurgy, Guizhou University, Guiyang 550025, China"},{"name":"Guizhou Key Laboratory for Mechanical Behavior and Microstructure of Materials, Guizhou University, Guiyang 550025, China"},{"name":"National & Local Joint Engineering Laboratory for High-Performance Metal Structure Material and Advanced Manufacturing Technology, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4951-630X","authenticated-orcid":false,"given":"Wei","family":"Li","sequence":"additional","affiliation":[{"name":"College of Materials and Metallurgy, Guizhou University, Guiyang 550025, China"},{"name":"Guizhou Key Laboratory for Mechanical Behavior and Microstructure of Materials, Guizhou University, Guiyang 550025, China"},{"name":"National & Local Joint Engineering Laboratory for High-Performance Metal Structure Material and Advanced Manufacturing Technology, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yilong","family":"Liang","sequence":"additional","affiliation":[{"name":"College of Materials and Metallurgy, Guizhou University, Guiyang 550025, China"},{"name":"Guizhou Key Laboratory for Mechanical Behavior and Microstructure of Materials, Guizhou University, Guiyang 550025, China"},{"name":"National & Local Joint Engineering Laboratory for High-Performance Metal Structure Material and Advanced Manufacturing Technology, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Moliu","family":"Han","sequence":"additional","affiliation":[{"name":"College of Materials and Metallurgy, Guizhou University, Guiyang 550025, China"},{"name":"Guizhou Key Laboratory for Mechanical Behavior and Microstructure of Materials, Guizhou University, Guiyang 550025, China"},{"name":"National & Local Joint Engineering Laboratory for High-Performance Metal Structure Material and Advanced Manufacturing Technology, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Liang","sequence":"additional","affiliation":[{"name":"College of Materials and Metallurgy, Guizhou University, Guiyang 550025, China"},{"name":"Guizhou Key Laboratory for Mechanical Behavior and Microstructure of Materials, Guizhou University, Guiyang 550025, China"},{"name":"National & Local Joint Engineering Laboratory for High-Performance Metal Structure Material and Advanced Manufacturing Technology, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"346","DOI":"10.1016\/j.msea.2016.07.043","article-title":"High-temperature flow characterization and microstructural evolution of Ti6242 alloy: Yield drop phenomenon","volume":"673","author":"Rezaee","year":"2016","journal-title":"Mater.
