Additional information

This contributed significantly to Wynne receiving the 2012 Harvey Flower Prize for titanium manufacturing. By combining unique in-house generated high temperature microstructure reconstruction software with software to describe crystallographic texture in friction stir welds we show bulk elastic stress to have a direct impact on beta to alpha transformation behaviour in Ti-6Al-4V. The key observation is that beta texture is simple shear relative to deformation axes but on transformation a strong variant selection is observed. This suggests emerging technologies such as additive manufacturing could control texture and therefore better properties by applying elastic stress fields.
