摘要

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.
