Abstract

The effect of dopant addition on the superplastic flow and tensile elongation in TZP was examined. ZrO₂-3mol%Y₂O₃-1.0mol%GeO₂-0.5mol% Nd₂O₃(TZP-1Ge-1Nd) exhibits higher tensile elongations of more than 600% at 1400°C and lower flow stresses than TZP(ZrO₂-3mol% Y₂O₃). This reduction in flow stress is mainly caused by the codoping of GeO₂ with other elements. The peak temperature for the nominal elongation decrease is shown by TZP-1Ge-1Nd, it is suggested that the reason for the maximum elongation with respect to temperature is caused by the reduction in flow stress of GeO₂ and that of restricted ductility at high temperatures due to Nd₂O₃.
