Research output: Contribution to journalArticle


This study focuses on grain motion in TZP (Tetragonal Zirconia Polycrystal) ceramics during superplastic deformation. The zigzag motion of grains was found in experimental data and analyzed statistically based on Brownian motion. At the beginning of deformation, constraint by surrounding grains is widely distributed, however, it becomes spatially uniform after 15% true plastic strain.
