Abstract
In the recent papers, 1,2 we presented a thermodynamic and kinetic model of the β→δ phase transformation (PT) in the organic energetic crystal octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX). It was based on the hypothesis that the kinetics of the β→δ PT is governed by the thermodynamics of melting of the δ phase. In particular, the activation energy for growth was found to be equal to the heat of fusion Δhδ→m . Nucleation was modeled empirically by the reversible first-order kinetics. The proposed kinetics described the experimental data quite well, however, a number of questions still remain.
