Abstract
The kinetics of the bulk melting of metals and other substances, wherein atoms independently join the growing liquid phase in all points of the interface, is studied. The frequency of the formation of the liquid nuclei is obtained as a function of the macroscopic parameters which are known from experiments. It is shown that ordinary metals can be superheated up to 150 to 200 °C above the melting temperature. The result is in accordance with the experiment. The near critical nucleus growth velocity is proved to be limited by the microscopic kinetics of melting and elastic forces are insignificant. The basic results are valid in the case of crystal nuclei formation also.Keywords
