Ferroelastic toughening in Pb ( Zr 1− x Ti x ) O 3 ( PZT ) ceramics can be augmented by phase transformation toughening through the inclusion of partially stabilized TZ ( PZT – Zr O 2 ). In order to deconvolve both these toughening modes, cubic Pb 1− y La y ( Zr 1− x Ti x ) O 3 ( PLZT ) with and without zirconia ( PLZT – Zr O 2 ) 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.
