电疲劳对掺镧锆钛酸铅陶瓷电致畴变行为的影响
DOI: 10.14062/j.issn.0454-5648.2015.03.07
Abstract:
在不同电疲劳周次下，对未极化掺镧锆钛酸铅铁电陶瓷在不同直流电场加载下得到的原位X射线衍射(XRD)谱和撤掉不同直流电场后得到的非原位XRD谱的(002)与(200)晶面衍射峰强与电场强度(EA)的关系进行研究。通过计算90°畴变体积分数发现，在电疲劳过程中，电场撤掉前后的90°畴变体积分数均随EA呈蝶形曲线变化。在低电场作用下，铁电畴更趋向于沿平行试样表面方向，而在EA=2000V/mm作用下，当电疲劳至106时，材料中有约5%的铁电畴被钉扎，有约6%的铁电畴在电场撤掉瞬间转回平行试样表面方向。电场撤掉后的90°畴变体积分数能直接反映铁电材料剩余极化程度。
