Abstract

Ferroelastic toughening in Pb(Zr1−xTix)O3 (PZT) ceramics can be augmented by phase transformation toughening through the inclusion of partially stabilized TZ (PZT–ZrO2). In order to deconvolve both these toughening modes, cubic Pb1−yLay(Zr1−xTix)O3 (PLZT) with and without zirconia (PLZT–ZrO2) was characterized. R curve and stress–strain behavior yielded a quantification of strong toughening and a lack for switching propensity that could be contrasted to PZT and zirconia-toughened PZT. A clear path for toughening of PZT for future application is therefore provided.
