Premelting of solid Fe at the contact with amorphous Ar at high pressure
S. V. Starikov and V. V. Stegailov
In this work we use molecular dynamics simulation to study the influence of the pressure medium on the surface melting of solid iron. The model under consideration is a two component system of solid Fe and amorphous Ar with a planar interface. Molecular dynamics simulations show that surface melting of solid Fe in contact with amorphous Ar begins at temperatures much lower than the melting temperature of the pure system. The dependence of the disordered layer thickness on temperature is obtained. A possible impact of these results on the interpretation of the DAC experiments is considered.
