Notes:
Work has been carried out recently, which demonstrates misorientation measurementsrecorded by using electron backscatter diffraction (EBSD) enables one to undertake local postmortem plastic strain quantification once the degree of misorientation is calibrated against plasticstrain. The present paper builds on this work and investigates the possibility of determining strain inindividual grains. Due to the anisotropy of crystalline grains, polycrystalline material deforminhomogeneously on a microstructural level. In this study, the local strain induced in a pure copperspecimen during tensile loading measured using EBSD was compared to in-situ strainmeasurements using optical microscopy imaging in conjunction with image correlation technique.By applying an averaging procedure for improving the accuracy of the measured EBSD data, thedistribution of the misorientation within grains was quantified, and, as one would expect, it tendedto be highest near the grain boundaries
