| 摘 要： | 用石英计测量了PZT-95/5陶瓷在冲击波作用下发生铁电－反铁电一级相变时产生的双波结构，相变起始压力约为0.5 GPa。对不同状态下的PZT-95/5陶瓷材料进行了扫描电镜电畴分析，结果表明，在该压力区域陶瓷发生了铁电－反铁电相变。

| Abstract: | Shock induced phase transition in PZT 95/5 ferroelectric ceramics was studied by using X cut quartz gauge. The stress profile measured shows definitely a two wave structure which indicates that the FE/AFE phase transition starts at stress about 0 5 GPa. SEM observations for the pre shock green samples, both polarized and un polarized, and for the post shock recovered samples provide clearly the unique microscopic features resulting from the transition. |
