Fig. 8.. Grain boundary contrast maps for Ti65 alloy deformed at 960 ℃ and 0.1 s-1 with different true strain (a) 0.04, (b) 0.4, (c) 0.7 and (d) statistical diagram of misorientation angle, (e) the α grain size histogram. The high-angle boundaries (HABs) with misorientation over 15 deg and the low-angle boundaries (LABs) with misorientation at 2 to 15 deg are depicted as black lines and red lines, respectively.
