摘要：

The parameters of the transformation into diamond or a diamond-like high-pressure phase under shock compression were measured for a pressed natural OSCh-T1 grade graphite, a highly oriented monochromator-grade graphite, and a UPV-1 pyrolitic carbon. In the experiments, the compression-wave structure was measured in the transformation region using a VISAR laser Doppler velocimeter. It was found that the transformation pressure increases and the transformation rate decreases as the degree of three-dimensional ordering of graphite decreases.
