| Abstract Scope |
This study investigates the plastic anisotropy of the Ti64 material captured via a uniaxial tensile test performed at nominal, intermediate, and high strain rates. The Lankford coefficients and the stress-strain curves were recorded while the tensile probing was done at angular increments of 15° between RD and TD. The role of texture and latent hardening were explored via the Visco-plastic Self-consistent (VPSC, a crystal plasticity model) modeling approach to explain the plastic anisotropy observed in the experiments. The interplay between self-hardening and latent hardening of the slip systems was found to have a strong influence on the Lankford coefficients measured at different strain rates. The modeling results suggested that the trend of Lankford values is only weakly governed by the initial texture. When the role of twinning was investigated, no direct evidence of its effect on the measured anisotropy was found. |
