Misorientation behavior of an aluminum bicrystal with 15.7 symmetric tilt boundary using simple shear

The misorientation behavior was investigated in the region of a symmetrical tilt \112[ boundary with a misorientation of 15.7 . The strain and orientation distributions were obtained by DIC (digital-image-correlation) and EBSD (electron backscattering diffraction) techniques to characterize the kinematical behavior of the grain boundary. In order to obtain a misorientation gradient, the misorientation was used in representation of the axis–angle description. This formation of the orientation gradient is found to have a common rotation axis in the [11–2] direction.
