Abstract
A new geometry of X-ray diffraction survey of single crystal in the
monochromatic X-ray radiation was used to obtain a diffraction patterns
of shock-compressed NaCl single crystals. Shock compression of the 2-mm
[100]-oriented single crystals backed with 0.7-mm graphite window was
produced by 6-mm Al impactors accelerated up to velocities 320-330 m/sec
in 25-mm pneumatic gun. The velocity of the free surface of the graphite
window was monitored by VISAR. In two shots the 30-nsec pulse X-ray
source was triggered after the arrival of the elastic precursor and the
plastic wave front at the NaCl-window interface. No evidence of the
transversal strain were found in the diffraction patterns of the
shock-compressed NaCl. The material seems to be able to maintain the
state of 1-D strain under intensive plastic deformation.
