摘要:

利用微分干涉相衬显微镜, 在垂直于极化方向的电场下, 对BaTiO₃单晶的畴变过程和单晶上压痕裂纹的变化过程进行了原位观察. 通过对压痕周围和远离压痕区畴变过程的对比, 研究了压痕对其周围畴变的影响. 结果显示, 面内极化试样在垂直于极化方向的面内电场作用下, 原有压痕和压痕裂纹随整个试样经历90^o畴变后也要发生变化, 变化后其形貌与在新的极化状态下重新压制的压痕相似; 对离面极化试样加面内电场时, 畴变速度先增大后减小, 畴变完成一半时, 速度最大; 而且畴变初始阶段速度呈现大小相间的振荡性.

Abstract：

As a ferroelectric material, BaTiO₃ single crystal has the domain structure which can be changed by the application of mechanical stress and electric field. Therefore, the fracture behavior of the crystal is closely related with the domain switching. To understand the relationship between the fracture behavior and the domain switching clearly, the change of the indentation cracks and domain switching around the indentation under electric field perpendicular to the polarization of the samples were investigated through in situ observations by a differential interference contrast microscopy. The results show that for in-plane polarized sample, after completion of domain switching under the in-plane electric field perpendicular to the polarization of the crystal, the indentation cracks and the domains around the indentation are the same as the new indentation on the sample with new polarization state. In the case of applying in-plane electric field on the anti-plane polarized sample, the speed of the domain switching increases in the initial stage and decreases in the end stage, it has the maximum value as half of the domain switching completed. And the speed fluctuates in the\linebreak first stage.

Key words： BaTiO₃ single crystal domain switching indentation crack fracture
