Study of Phase Transitions in Cerium by Pressure Gauge PVDF
ORAL
Abstract
This paper examines phase transitions in cerium during shock compression using PVDF gauges. A two-wave structure was observed with loading pressures of 4GPa~- 12GPa. The wave structure consists of leading isentropic compression wave followed by a shock wave. This wave structure was formed as a result of the isomorphic ($\gamma -\alpha )$ phase transition. The wave profiles exhibited no peculiarities resulting from the polymorphic transition ($\alpha -\varepsilon )$ as predicted by Elkin et. al [\textit{Proceedings of the International Conference VII Khariton Readings, }Sarov 2005, p. 116].
