چکیده انگلیسی
The effect of frequency on the electrical fatigue, crack growth and domain switching in Pb(Mg1/3Nb2/3)0.65Ti0.35O3 ceramics has been investigated. The changes in microstructure, ferroelectric properties and domain-switching behavior of samples fatigued at 1, 10, 50 and 100Â Hz were determined. In this experiment, we found that the thickness of the damaged layer under the electrodes and the crack length decrease with increasing frequency. The remnant polarization decreases while the coercive field increases with an increasing number of loading cycles. A domain orientation map around the crack tip was revealed using scanning high-energy X-ray diffraction from a synchrotron source. This showed the effect of fatigue frequency on the lattice strain distribution and ferroelectric domain texture around the crack tip.
