Surface melting of superheated crystals. Atomistic simulation study

Melting front velocity dependencies on temperature are calculated using the molecular-dynamics method for the EAM models of Al and Fe as well as for the Lennard-Jones system. Different surface orientations are considered. It is shown that the Broughton–Gilmer–Jackson theory of the collision-limited growth can describe the results obtained. The isochoric bulk solid melting and decay under ultrafast heating is simulated for mono- and polycrystalline models.
