Abstrakt: The phase composition, microstructure, and mechanical properties of rapidly solidified foils of Sn–Zn eutectic alloys doped with antimony are studied. The alloy foils have a uniform distribution of components. The rapidly solidified eutectic consists of dispersed precipitates of a zinc phase distributed in a tin matrix; antimony forms an intermetallic compound with zinc. The rapidly solidified eutectic alloy doped with antimony has a microcrystalline structure, and no texture is observed. Twins are formed in eutectic alloys with antimony when grain sizes are small. The microhardness of the foils increases with an increase in concentration of antimony. The supersaturated solid solution decomposes at room temperature during holding of rapidly solidified foils. The annealing of foils leads to a decrease in microhardness and growth of the microstructure. [ABSTRACT FROM AUTHOR]
