Abstract

The purpose of this study is to fabricate high-strain rate above 10 ^-2 s^-1 superplastic zirconia systems. Dense, homogeneous and fine-grained zirconia systems of MgO and TiO₂ added 3YTZ (3mol%Y₂O₃ doped tetragonal zirconia), and Al ₂O₃ and/or Mn₃O₄ added 3YTZ were obtained by colloidal processing The grain growth was controlled by cation lattice diffusion and the grain growth rate was enhanced by adding TiO ₂, Al₂O₃ and/or Mn₃O₄. High-strain rate superplasticity was established for the systems of 3(Y ₂O₃, MgO) · 97(Zr_0.95Ti _0.05)O₂ and small amounts of Al₂O₃ and/or Mn₃O₄ added 3YTZ. Such excellent superplasticity is due to the homogeneous, fine grained microstructure and enhancement of cation lattice diffusion in 3YTZ by addition of TiO₂, Al₂O ₃ and/or Mn₃O₄.
