ABSTRACT
Since superlattice reflections in PbZr0.52Ti0.48O3 ceramics have been observed clearly at low temperature by means of electron diffraction [Citation1, Citation2], antiphase boundaries(APBs) and 180°-antiphase boundaries(180°-APBs) are suspected to appear. And the appearance of APBs and 180°-APBs will influence the fatigue property of the ceramics. Then low temperature fatigue behaviors of PbZr52Ti48O3 ceramics were investigated. The results suggest that the fatigue property were improved.
