ABSTRACT
In alloys with a primarily crystallized aluminum solid solution the structure is a set of different elements of the internal grain structure and the eutectic colonies (or the degenerate eutectic) at the boundaries of dendritic cells (Zolotorevskii, 1981); The structure in alloys of the eutectic composition is a set of different elements of the internal structure of the eutectics; In alloys, where iron-containing or other phases (for example, silicon in silumins) are primarily crystallized, the structure is a set of different elements of the structure of these phases, as well as the phases formed by the eutectic or peritectic reactions (including the aluminum solid solution).
