Recovery experiments on porous PZT 95/5 ferroelectric have been performed on a single-stage compressed gas gun over the stress range of 0.3 to 4.6 GPa. Density measurements on the recovered specimens suggest permanent pore compaction. X-ray diffraction analysis indicates that the shock-induced FE to AFE phase transformation is reversible, with a reduction in the residual lattice strain compared with the unshocked material. SEM and TEM microscopy show evidence of ferroelectric domains with fewer numbers at the higher stress. The microstructure of the 3.0 GPa sample is significantly affected as evidenced by dislocation slip bands and oval shaped voids.
