Kinetic melting and crystallization stages of strongly superheated and supercooled metals

Within the framework of the molecular dynamics approach was carried out modeling of heterogeneous melting/crystallization of metals with different crystallographic lattices under conditions where the phase front propagates on overheated/supercooled media. To obtain the temperature dependence of the kinetic velocity in analytical form results of atomistic modeling were approximated by function obtained from the kinetic representations. For the first time were built stationary temperature dependences of kinetic velocity $v(T_{sl})$ for limit values of overheated/supercooling of copper and iron.
