Abstract

High-resolution X-ray diffraction (XRD) line-profile analysis was used to characterize slip activity and twinning in commercial-purity titanium (CP-Ti) during hot rolling. The effect of {10.1} and {10.2} twins on XRD patterns was deduced using the DIFFAX software. The density of twin boundaries was then incorporated into the XRD pattern-fitting procedure for evaluating dislocation densities, slip activity, and subgrain size. It was found that 〈a〉 and 〈c + a〉 type slip occurred during hot rolling. The X-ray data revealed 0.07(±0.02)% twin-boundary frequency for the {10.2} twin family, but zero twinning (within the experimental accuracy) in the {10.1} family. Electron backscatter diffraction (EBSD) data confirmed the X-ray findings.
