【 摘 要 】

For a solution of the problem of modification of a microstructure of cast alloys it is necessary to accept admission that crystallization centers of crystals of phases are the crystalline buildups consisting of nanocrystals of phases. The role of modifiers comes down to lower concentration in a metal melt of the dissolved surface-active elements and gases and (or) to formate of the moistened substrates on which process of gas generation and deleting gas bubbles will be most preferable.
