MOLECULAR DYNAMICS MODELLING OF LIFETIME AND DECAY OF METASTABLE CRYSTALS UNDER SUPERHEATING OR STRETCHING

In this work we consider the decay and stability boundary of metastable defect-free Lennard-Jones crystal. The developed approach allows us to calculate the lifetime of the metastable phase via molecular-dynamics simulation. We apply our approach to both types of metastable solid: superheated and stretched. Homogeneous nucleation of melt and voids is examined. The temperature dependence of nucleation rate is calculated and kinetic limit of stability is estimated. The results are compared with the recently published experimental-based solid Ar spinodal.
