| Abstract Scope |
Forming of Ti-6Al-4V sheet is often done at elevated temperature to achieve the needed ductility to create complex shapes. The current study seeks to achieve ductility enhancement at room temperature through the cyclic bending under tension (CBT) process, which has been shown in prior work to delay work hardening and necking through an oscillating stress superimposed on a tensile load. Delayed necking and trace analysis of slip patterns are observed through high resolution digital image correlation (HRDIC). The delayed work hardening of the material is assessed by analyzing the density of geometrically necessary dislocations (GNDs) for progressively greater levels of plastic strain. GND populations are observed and quantified through electron backscatter diffraction (EBSD) and x-ray diffraction (XRD). The GND densities from these tests is used to inform a predictive model that will assess feasibility of fabricating useful parts at room temperature. |
