Microstructure Evolution of Commercial Pure Titanium During Interrupted In Situ Tensile Test

Microstructure evolution of commercial pure titanium is investigated by interrupted in situ electron backscatter diffraction (EBSD) measurement during tensile deformation along transverse direction at room temperature. After 24 pct elongation, the split basal texture initial material weakened and rotated around 90 deg normal (ND). $${{11}\bar{2}{{2}}}$$ - $${{10}\bar{1}{{2}}}$$ double twin main reason for change texture. The poles are nearly perpendicular to ND primary back through reorientation secondary twin. Both Schmid factor criterion displacement gradient accommodation considered predict twin-induced TD tension. Kink bands formed accumulation 〈a〉 dislocations also observed deformed grain. activation other slip systems can deviate rotation axis reduce angle kink boundary. Besides, boundary with high dislocation density obviously hinders transmission simultaneously be taken as a preferential nucleation site
