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
The high-strain-rate superplasticity of a ZrO 2 -spinel composite exhibits a sigmoidal strain rate-stress relationship. At high strain rates, a strain rate sensitivity of m % 0.25 can be ascribed to the intervention of plastic deformation. At intermediate and low strain rates, the decreasing m-value
