Abstract
<jats:p><jats:underline>It is shown that intermetallic metals of the modifying ligatures are not the crystallization centers of primary crystals of a </jats:underline>a<jats:underline>-phase. As the main demodifier serves hydrogen dissolved in liquid silumin. For a solution of the problem of modifying of primary crystals of a </jats:underline>a<jats:underline>-phase in castings from silumins it is necessary to accept a presumption that crystallization centers of primary crystals of a </jats:underline>a<jats:underline>-phase are the crystalline developments consisting of </jats:underline>a<jats:underline>-phase nanocrystals, and the role of the modifying intermet...
