[Issue Author Index][Volume Author Index]
[Cover illustration] Cover illustration: Pole figures depicting the angular change of lattice plane normals for four applied deformations (see Poshadel, Dawson and Johnson, pages 237-244). These images illustrate how insufficient pole figure coverage introduces ambiguity between correct and other plausible deformation modes, which inherently limits component-wise resolution of the strain tensor.

Assessment of deviatoric lattice strain uncertainty for polychromatic X-ray microdiffraction experiments

A. Poshadel, P. Dawson and G. Johnson

Synopsis: An in situ loading experiment demonstrates differences in uncertainties among deviatoric lattice strain components measured using polychromatic X-ray microdiffraction. Monte Carlo simulations show that the differences in uncertainties are caused by spurious deformation modes that arise erroneously in the strain calculation owing to measurement noise and limited pole figure coverage.
