Abstract Scope Deformation of a grain is highly influenced by neighboring grain deformation, as all grains impose boundary conditions on each other that vary spatially. To investigate this effect, detailed experimental measurements of heterogeneous deformation that obtain local stress and strain measurements using high energy x-ray diffraction are used to obtain spatially resolved strain data. Comparisons between such data sets for titanium alloys and simulations using crystal plasticity simulation codes have mixed success – often the closer one looks at the results, the worse the correlations look. Potential reasons for discrepancies in computational simulations include the lack of modeling of dislocation substructure, strain rate sensitivity differences in different slip families, ignoring internal stress states initially present in annealed material, among other reasons yet to be clarified. Supported by DOE/BES contract DE-FG02-09ER46637, and DOE and NSF, respectively, for the Advanced Photon Source beamlines 1 and 34, and CHESS beamline F2.
