| Abstract Scope |
Microtextured regions (or macrozones) in Ti-6Al-4V have been witnessed to facilitate the formation of long-range strain localization prior to the onset of macroscopic yield, which affects the mechanical performance of the material. The character of microtexture that leads to this behavior has not been widely studied. In this study, a crystal plasticity finite element solver is employed to simulate the deformation response of a suite of samples exhibiting microtextured regions, where both the nominal orientation and the intensity of microtexture are parameterized. Additionally, scanning electron microscope digital image correlation experiments are performed on a sample exhibiting a strong microtextured region. The heterogeneity of plastic strain within the simulated and experimental microtextured regions is calculated, providing a quantitative assessment of degree of strain localization. Results - specifically the microtexture conditions which facilitate the formation of long-range strain localization, and the underlying micro-mechanical influences - are discussed. |
