In this paper, the origin of the threshold stress in pure 3 mol %-yttria tetragonal zirconia polycrystals (YTZP) is analysed in detail. At this regard, the two explanations reported in literature are discussed thoroughly. One of them invokes dislocation activity as the origin for such quantity, wher
The doping amount and temperature dependence of superplastic flow in a TiO 2 -and/or GeO 2 -doped tetragonal ZrO 2 polycrystal (TZP) were investigated in the doping range of 0.2-8 mol.% and in the temperature range of 1200-1550 Β°C. While the tensile ductility in the TZP is significantly improved by
