Abstract
This paper focuses on grain motion during superplastic deformation in TZP (Tetragonal Zirconia Polycrystal) ceramics. After estimation theory for random force was developed, the kinetic data of grains were stochastically analyzed, and random force acting on grains was estimated: At an earlier stage of superplastic deformation, distribution of random force differs between the loading direction and its normal direction. As superplastic deformation advances, however, it becomes identical in two directions. Such the change in the random force is discussed in terms of constraint by surrounding grains.
