Popis: | The growth rate of nuclei is calculated in self-consistent mean field approximation with allowance for the screening of a selected nucleus from heat fluxes, and an expression is obtained for the screening length of the heat flux. It is shown that the growth rate of a nucleus depends on the degree of crystallization of the melt. The influence on the crystallization process of collisions of the particles as they coalesce into a polycrystalline solid is investigated. A refinement of the size distribution function in the thermal Ostwald ripening stage is obtained. |
