N2 - Work hardening behavior of Ti-15Mo alloy (mass %) was examined through quantitative evaluation of the {332}〈113〉 twinning structural evolution at various plastic strain levels by optical microscope (OM) observations combined with electron backscatter diffraction analyses (EBSD). Based on analyzed images from the optical micrographs, area fraction of twins rapidly increases to 40% at strain of 0.05, and gradually reaches to 52% at strain of 0.12. With further deformation to a strain of 0.17, it has no significant change. The EBSD inverse pole figure maps exhibit that the twins become denser and thicker with increasing strain. A linear relationship is found between true stress and inverse square root of mean free path of dislocations at strain up to 0.12, indicating that the work hardening is mainly dominated by dynamic microstructure refinement induced by the twinning.
