    • Abstract


      The grain boundary character distribution and annealing twins in a multifunctional 𝛽-type Ti–23Nb–0.7Ta–2Zr–O alloy having a stable bcc phase structure are investigated by electron backscattering diffraction (EBSD). The results show that the coincident site lattice (CSL) boundaries, including 𝛴 3 and 𝛴 11 twin boundaries mainly form at the early stage of recrystallization. {112}$\langle$111$\rangle$ and {332} $\langle$113$\rangle$ annealing twins are observed to occur in the completely recrystallized Ti–23Nb–0.7Ta–2Zr–O alloy.
