| Abstract Scope |
Titanium alloys play a key role in enabling lighter, more reliable aerospace components but are inherently limited by their hexagonal close-packed crystal structures. The slip systems with the lowest critical resolved shear stresses are on the basal and prismatic planes which only provide four independent slip systems, all in the <a> direction family, resulting in inherent ductility limitations and strong texture dependence. This has most recently been addressed by c/a ratio engineering to activate <c+a> slip at lower stress levels, but the effects of this strategy have only been investigated under quasi-static tension. In this study, we demonstrate that c/a ratio engineering is not only an effective means of improving the quasi-static tensile properties of titanium alloys, but also effective in improving their performance under dynamic loading conditions. The underlying mechanisms contributing to such improvement are examined through a coupling of in-situ SEM/EBSD characterization and high-energy X-ray diffraction techniques. |
