Abstract Scope |
Commercially pure (CP) titanium having hexagonal structure exhibits unusual anisotropy and asymmetry at room temperature. Activation of various slip and twinning is known to cause the complex deformation behavior of CP titanium. In this study, deformation behavior and microstructure variation in CP titanium were examined using in-situ tensile test and the crystal plasticity finite element analysis. The material parameters for the crystal plasticity model were calibrated using the macroscopic behavior under various loading conditions. The activated slip system was evaluated from observed slip traces. The deformation behavior in each grain with various orientations was investigated quantitatively. Prismatic slip system was dominant and tensile twinning was activated in CP titanium with lower oxygen content. |
