On the correlation between macrozones and twinning in Ti–6Al–4V at very high strain rates

The optimization of Ti–6Al–4V structures for impact loading events requires understanding of the effects of macrozones (or micro-texture) on the high strain rate behavior of Ti–6Al–4V. In this paper, electron backscatter diffraction analysis of the pre- and post-deformation microstructures from a Taylor impact specimen shows that macrozones have a significant effect on the activation of deformation twins in Ti–6Al–4V at very high strain rates.
