The grain boundary character distribution and annealing twins in a multifunctional beta-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 Sigma 3 and Sigma 11 twin boundaries mainly form at the early stage of recrystallization. {112}< 111 > and {332} < 113 > annealing twins are observed to occur in the completely recrystallized Ti-23Nb-0.7Ta-2Zr-O alloy.
