Abstract
The deformation texture of pure polycrystalline tantalum was characterized in the range of strain rates from 10−3 ∼10+3 s−1 at room temperature. Quasi-static tests were carried out on an MTS servohydraulic machine, whereas dynamic tests were carried out using a split Hopkinson pressure bar. Texture measurements were done using the electron backscattered diffraction set-up in the scanning electron microscope chamber. It was observed that the deformation texture was unaffected qualitatively by the strain rate variations, and was correlated to the insensitivity of the hardening behavior at different strain rates. Strain softening at high strain rate seemed to sharpen the texture.
