Theoretical Basis for Understanding the Mixed Phase Region in Shock-Compressed Iron

Abstract

Under the influence of shock waves, certain materials undergo polymorphic transformations. The time available in a shock experiment for such a transformation to occur does not exceed a few microseconds, yet the same transformation may require minutes or hours for completion in a static experiment. This large transformation rate is the result of distinct features of nucleation and growth of new phases in shock waves. Predominant among these features are the large number of low energy nucleation sites available on defects created by shock waves. Research on nucleation and growth of the new phase in shock-loaded solids is important for developing quantitative physical models for transformation rates and thermodynamic State paths through the mixed phase region.
