摘要

摘要: 采用一级气体炮加载装置，利用加窗VISAR技术，对极化和未极化两种状态的PZT 95/5铁电陶瓷进行了逆向冲击实验，在0.52~3.8 GPa冲击压力范围内，得到了PZT 95/5铁电陶瓷两种状态的-u关系。对比文献已有实验数据显示，PZT 95/5铁电陶瓷的Hugoniot曲线与初始密度值密切相关，高密度的PZT 95/5铁电陶瓷在0~3.0 GPa压力范围内的-u关系接近线弹性，较低压力下不同极化状态的Hugoniot数据表明，PZT 95/5铁电陶瓷发生了冲击相变。

Abstract: Reverse-impact experiments were conducted on a gas-gun facility to determine the poled and unpoled PZT 95/5 ceramic Hugoniot states. Instrumented VISAR recorded the u-t profile at the interface between the buffer and window. Comparisons between the obtained results and reference data indicated that Hugoniot curves for PZT 95/5 ceramic are quite sensitive to the differences in initial density. Hugoniot curve of higher density PZT 95/5 ceramic shows that the -u curve is in linearity below 3.0 GPa. The Hugoniot curves for the unpoled PZT 95/5 ceramic and poled PZT 95/5 ceramic have also been obtained. In addition, the phase transition of FR/AO has been identified over the stress range of interest.
