摘要：
A complex study of the crystallographic texture of corundum ceramics obtained by spark plasma sintering (SPS) has been performed. It is found that a characteristic texture state is formed along the direction of applied compressive load. It is shown that dislocation slip in the basal planes of the corundum lattice during plastic deformation is a possible mechanism of formation of this texture type. The values of microhardness of SPS ceramics in the directions parallel and perpendicular to the axis of the applied compressive load are found to be 16.2 +/- 0.8 and 14.9 +/- 0.8 GPa, respectively.
