  • 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.
