Abstract

Texture formation via high‐temperature deformation in sintered alumina was investigated. Fine‐grained, normal‐purity‐alumina sintered bodies deformed under stresses up to 80 MPa in a temperature range of 1200°–1300°C. Fine, disklike grains formed in the equiaxial fine‐grained matrix during high‐temperature deformation and aligned unidirectionally via material flow during deformation. Highly textured sintered alumina bodies were obtained via high‐temperature deformation and further annealing.
