Abstract
Transmission electron diffraction from repeatedly rubbed α-alumina revealed a structure that was created as the sum of the contributions of several different aluminas. Owing to the lack of regularity in the atomic arrangement, this structure may not be considered as being crystalline although it is not an amorphous structure. The transformation to this state can be one of the mechanisms of plastic deformation during repeated rubbing.
