Creep Behavior of Pore-Free Polycrystalline Aluminum Oxide
Creep in pore-free polycrystalline aluminum oxide has been studied as a function of temperature, grain size, and strain rate. The behavior may be described byσαd2ε̇, where d is the mean grain diameter. Deformation is not controlled by basal slip but by a diffusional creep process as described by Nab...

| Zusammenfassung: | Creep in pore-free polycrystalline aluminum oxide has been studied as a function of temperature, grain size, and strain rate. The behavior may be described byσαd2ε̇, where d is the mean grain diameter. Deformation is not controlled by basal slip but by a diffusional creep process as described by Nabarro and Herring, [F. R. N. Nabarro, Conference on Strength of Solids (The Physical Society, London, 1948), p. 75; C. Herring, J. Appl. Phys. 21, 437 (1950)]. |
