The effect of GeO₂ addition on the superplasticity flow and tensile ductility in TZP was examined. ZrO₂-2.5mol%Y₂O₃-1.0mol% GeO₂ (TZP-lGe) exliibits lower flow stress and larger tensile elongation than ZrO₂-2.5mol%Y₂O₃ (2.5Y-TZP) in a temperature range of 1200 and 155CTC. This reduction in flow stress is mainly caused by a reduction in activation energy ibr plastic flow. Cation's difiusivity must be enhanced by the presence of GeO₂ in TZP. The enhanced ductility in TZP-lGe can be explained by the reduction in flow stress.
