Description
Summary:The heterogeneous melting/crystallization of metals with different crystallographic lattices in conditions where the phase front propagates on overheated/supercooled media was modeled in the context of the molecular dynamics approach. In order to obtain the temperature dependence of the kinetic velocity in analytical form, the results of atomistic modeling were approximated by the function obtained from the kinetic representations. For the first time, stationary temperature dependences of kinetic velocity ν( T s ℓ) for the limit values of superheated/supercooled copper and iron were built.
