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.
