摘要：

The authors report the first experimental observation of sequential, multiple polymorphic phase transformations occurring in praseodymium dynamically compressed using a ramp wave. The experiments also display the signatures of reverse transformations occurring upon pressure release and reveal the presence of small hysteresis loops. The results are in very good agreement with equilibrium hydrodynamic calculations performed using a thermodynamically consistent, multiphase equation of state for praseodymium, suggesting a near-equilibrium transformation behavior.
