title = "Influence of Grain Size and Strain Rate on the Constitutive Response and Texture Evolution in High-Purity Titanium",
abstract = "The effect of strain rate, temperature, grain size, and texture on the substructure and mechanical response of high-purity polycrystalline titanium is presented. The compressive stress-strain response of 20 and 240 µm grain size high-purity Ti was found to depend on both the applied strain rate, test temperature, and crystallographic texture. The substructure of high-purity Ti deformed at high-strain-rate or quasi-statically at -196°C (77K) displayed a higher incidence of deformation twinning than during quasi-static deformation at 25°C (298K) as characterized using electron backscatter diffraction. Coupling of MTS constitutive modeling of the mechanical behavior with Taylor cylinder testing and finite-element simulations of the Taylor-cylinder impact testing is shown to provide an effective means to validate the high-strain-rate constitutive behavior of high-purity Ti.",
