At the strain rate of 1.8 \u00d7 104 s\u22121 induced by a split Hopkinson pressure bar, the shear stress reaches a maximum of 1951 MPa with the shear strain of 1.27. It is found that the \u03b1+\u03b2 dual-phase colony structures mediate the extensive plastic deformations along \u03b1\/\u03b2 phase boundaries, contributing to the formations of ASBs, microvoids, and cracks, and resulting in stable and unstable softening behaviors. Moreover, the dynamic recrystallization yields the dispersion of a great amount of fine \u03b1 grains along the shearing paths and in the ASBs, promoting the softening and shear localization. On the contrary, low-angle grain boundaries present good resistance to the formation of cracks and the thermal softening, while the non-basal slipping dramatically contributes to the strain hardening, supporting the promising approaches to fabricate the advanced damage tolerance dual-phase Ti alloy.<\/jats:p>","DOI":"10.3390\/ma14082044","type":"journal-article","created":{"date-parts":[[2021,4,19]],"date-time":"2021-04-19T11:21:38Z","timestamp":1618831298000},"page":"2044","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Effect of High Strain Rate on Adiabatic Shearing of \u03b1+\u03b2 Dual-Phase Ti Alloy"],"prefix":"10.3390","volume":"14","author":[{"given":"Fang","family":"Hao","sequence":"first","affiliation":[{"name":"State Key Laboratory of Solidification Processing, Northwestern Polytechnical University, Xi\u2019an 710072, China"},{"name":"Western Superconducting Technologies Co., Ltd., Xi\u2019an 710018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuxuan","family":"Du","sequence":"additional","affiliation":[{"name":"Western Superconducting Technologies Co., Ltd., Xi\u2019an 710018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peixuan","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Solidification Processing, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youchuan","family":"Mao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Solidification Processing, Northwestern Polytechnical University, Xi\u2019an 710072, China"},{"name":"Western Superconducting Technologies Co., Ltd., Xi\u2019an 710018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deye","family":"Lin","sequence":"additional","affiliation":[{"name":"CAEP Software Center for High Performance Numerical Simulation, Institute of Applied Physics and Computational Mathematics, Beijing 100088, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Solidification Processing, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingyu","family":"Gao","sequence":"additional","affiliation":[{"name":"Laboratory of Computational Physics, Institute of Applied Physics and Computational Mathematics, Beijing 100088, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaixuan","family":"Wang","sequence":"additional","affiliation":[{"name":"Western Superconducting Technologies Co., Ltd., Xi\u2019an 710018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianghong","family":"Liu","sequence":"additional","affiliation":[{"name":"Western Superconducting Technologies Co., Ltd., Xi\u2019an 710018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haifeng","family":"Song","sequence":"additional","affiliation":[{"name":"Laboratory of Computational Physics, Institute of Applied Physics and Computational Mathematics, Beijing 100088, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Feng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Solidification Processing, Northwestern Polytechnical University, Xi\u2019an 710072, China"},{"name":"Western Superconducting Technologies Co., Ltd., Xi\u2019an 710018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinshan","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Solidification Processing, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8814-525X","authenticated-orcid":false,"given":"William Yi","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Solidification Processing, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"335","DOI":"10.1038\/nature08692","article-title":"Strong crystal size effect on deformation twinning","volume":"463","author":"Yu","year":"2010","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"931","DOI":"10.1038\/nmat4340","article-title":"Dislocation locking versus easy glide in titanium and zirconium","volume":"14","author":"Clouet","year":"2015","journal-title":"Nat.
