The structure of condensates and cast samples of aluminium, Al–Fe and Al–Zr alloys crystallized from both the melt and the vapour phase in a vacuum is studied. As shown, the alloying of the vapour flow of a matrix metal, i.e. aluminium, with iron up to $\cong$ 3 at.% reduces the grain size of condensates from 2 $\mu$ m to 50 nm. The dispersing effect of iron and zirconium on the grain structure of aluminium is demonstrated on the castings of this metal, where a decrease in the grain size is observed by more than one order of magnitude. Refinement of the grain structure of aluminium is explained by the formation of the grain-boundary segregation by atoms of alloying elements during crystallization from both the vapour and the melt.

Key words: condensation, crystallization, segregation, grain size, aluminium.
