MAIN DIFFICULTIES OF THE MODERN METAL FUSION’ THEORY OF CRYSTALLIZATION. WAYS OF OVERCOMING
Abstract
The main difficulties of the modern theory of crystallization of metal fusion are imperfect ideas of a structure of fusions, processes of origin and growth of crystals and influence of nonmetallic particles and the dissolved gases. In order to overcome these difficulties it is necessary to assume: fusions consist of stable nanocrystals and atomic unstructured zones; the centers of crystallization of phases are formed of nanocrystals of these phases; the basic construction elements of crystals are not atoms, but nanocrystals; nonmetallic particles play a supporting role in the course of crystallization; the dissolved gases exert direct impact on formation of crystals and their morphology.
