The distribution and some characteristics of grain boundaries have been determined in three samples of fine‐grained Mg‐doped alumina which had undergone different thermo‐mechanical treatments: as‐pressed at 1500°C, stress‐free annealed, and deformed at the same temperature. The analyses of some particular features point out the role of the grain‐boundary type “special’ or “general’ on the creep deformation mechanisms.
