Description The effect of orientation and interaction with neighboring grains in polycrystalline Ti6Al4V deformation are quantified using interrupted deformation coupled with microstructure analysis. It is shown that softer grains accommodate more strain compared to hard basal grains, which can be explained in terms of their resolved shear stress and critical resolved shear stress. Grains with similar orientations follow different orientation trajectories during deformation depending on their misorientation with respect to neighboring grains. The influence of near neighbor interaction is quantified using a new parameter, average nearest neighbor misorientation (NNM). The NNM accurately predicts similarities and differences in the evolution of grain orientations during deformation. (C) 2015 Elsevier B.V. All rights reserved.
