Dislocation structure of 10° low-angle tilt grain boundary in α-Al2O3 has been observed by high-resolution electron microscopy (HRTEM). It was found that perfect 〈112̄0〉 edge dislocations, which are introduced to compensate the misorientation, dissociated into two mixed partial dislocations with {112̄0} stacking-fault in between. The distances between the two partials were estimated by the force balances between repulsive forces of periodical dislocations and attractive forces from stacking-fault. The stacking-fault energy for 10° low-angle tilt grain boundary was estimated to be much higher than the previously reported value.
