【 摘 要 】

We report on nanosecond resolution lattice measurements of shock-compressed Mg in the hcp and bcc phases between 12 and 45 GPa. X-ray diffraction signals consistent with a compressed bcc lattice were captured above a shock pressure of 26.2 +/- 1.3 GPa. Our results are in agreement with the phase boundary calculated by Moriarty and Althoff using the generalized pseudopotential theory in the pressure and temperature region intersected by the principal shock Hugoniot.
