Abstract

This paper examines phase transitions in cerium during shock compression using PVDF gauges. A two‐wave structure was observed with loading pressures of 4 GPa⩽P<12 GPa. The wave structure consists of a leading isentropic compression wave followed by a shock wave. This wave structure was formed in cerium as a result of the isomorphic (γ‐α) phase transition. The wave profiles exhibited no peculiarities resulting from the polymorphic transition (α‐ε) in the aforementioned pressure range.
