Abstract
Optical and x‐ray diffraction observations are reported for lithium niobate crystals which have been subjected to shock loading along the c axis and recovered for post‐shock study. At pressures of 3.5 and 5.5 GPa, no unusual x‐ray diffraction results are observed. Optical observations on these samples show planar features similar to prior observations in other crystals. At 9.5 and 19 GPa, the x‐ray observations indicate that the samples are ‘‘recrystallized’’ into micron size crystallites with well coordinated crystallographic alignment changes from the original crystal axis. The observed effects are thought to be initiated by localized heating accompanying heterogeneous yielding.
