In the initial stage of compression (elastic deformation), the stress and strain are proportional, and the stress\u2013strain curve is a straight line. In the plastic deformation stage, the flow stress decreases significantly with the increase of deformation temperature, while the strain rate has no significant effect on the flow stress during dynamic compression. A constitutive model has been established to predict the flow stress, and the relative error is 2.32%. It is shown by observing the microstructure that when the deformation temperature is 293 \u00b0C, and the strain rate reaches 1600 s\u22121, a shear band with an angle of about 45\u00b0 to the axial direction of the specimen appears, and the severe shear deformation makes the \u03b1 phase in the shear band fibrous and contains high-density dislocations. The formation process of the shear band and its influence on fracture are analyzed and discussed.<\/jats:p>","DOI":"10.3390\/ma15217599","type":"journal-article","created":{"date-parts":[[2022,10,30]],"date-time":"2022-10-30T07:26:50Z","timestamp":1667114810000},"page":"7599","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Dynamic Deformation Behavior and Fracture Characteristics of a near \u03b1 TA31 Titanium Alloy at High Strain Rates"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8023-6205","authenticated-orcid":false,"given":"Weixin","family":"Yu","sequence":"first","affiliation":[{"name":"School of Mechanical and Electrical Engineering, Xinxiang University, Xinxiang 453003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaofen","family":"Li","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electrical Engineering, Xinxiang University, Xinxiang 453003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinyong","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Materials and Physics, China University of Mining and Technology, Xuzhou 221116, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shusen","family":"Hou","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electrical Engineering, Xinxiang University, Xinxiang 453003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yifan","family":"Lv","sequence":"additional","affiliation":[{"name":"Luoyang Ship Material Research Institute, Luoyang 471000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"225","DOI":"10.1016\/j.ijplas.2016.03.006","article-title":"Characterization and modeling of mechanical behavior of single crystal titanium deformed by split-Hopkinson pressure bar","volume":"82","author":"Morrow","year":"2016","journal-title":"Int.
