 Abstract: Britton criticizes the accuracy of the stress value obtained from electron backscatter diffraction (HR-EBSD) and surmises that the rotation field rather than rotation gradient field was used during geometrical necessary dislocations (GND) calculation process. It is our opinion, however, that the topic of the absolute values of the stresses based on cross correlation and the HR-EBSD technique is not discussed at all in our paper. Our paper is focused rather on relative values (the evolution of stress/strain partitioning at different tensile strains) but not on absolute values. It should, however, be mentioned that, due to the high orientation changes within grains, the error for stress measurements may be considerable, as pointed out by Britton. The stress measurements should, therefore, be regarded with care. We have checked the GND calculation code carefully and we confirm that the correct rotation gradient field data is adopted in the GND calculation process.
