Release time:2016-04-19 Affiliation of Author(s):Central South University Journal:Materials Science and Engineering A Place of Publication:us Abstract:Ultrafine grained titanium has unique mechanical properties and attracts tremendous interest due to its scientific and technological application. Shear localization is frequently denoted as adiabatic shear band, and is one of the most important deformation and failure mechanisms for it used at high rate deformation. Hat shaped specimens are used to induce the formation of an adiabatic shear band under controlled dynamic conditions. Unstable shear deformation of the alloy emerges after the true flow stress reaches about 750 MPa, the first vibration peak during the split Hopkinson pressure bar t Co-author:Zhaolin Liu, Xiaoyan Wang, Jieying Sun, Juan Li, B.F.
