Experimental data analysis methods for the physics-based description of phase transition kinetics

Experimental data analysis techniques for the determination of phase transformation kinetics under ramp compression are presented. The new techniques, which do not require any simulations, are described in three parts: (I) estimation of nucleation and growth rates via analysis of the velocimetry wave profile “loop”, (II) bounding of the metastability limit or “maximum over-pressurization” and (III) application of a universal scaling relation that sheds light on the time-dependence of the phase transition. The relatively simple analysis techniques presented are made available in an open source code for the community.
