, Shenyang 110004, China) Abstract: The grain boundary characterization and its influence on the fatigue sliding band initiation and short crack propagation in Ti-15-3 sheet were studied. The results... with misoritation angle of 40?-60? are over 60%, the adjacent grains with misoritation angle less 15? are about 4%. The fatigue sliding band preferres to initiate near the large-angle grain boundary, which shows......
