Phase-transformation toughening of antiferroelectric ceramics

摘要

Antiferroelectric (AFE) ceramics,which can undergo a reversible phase transition to a ferroelectric(FE) state under an applied electric field,are promising candidates for energy storagefor high energy-density and high power-density applications.Experiments show that the AFE-FEphase-transition induces a large volumetric strain in addition to the deviatoric strain of transformation.
