N2 - The structural-phase state of a powder mixture of copper and tin (X = 12–20 wt % Sn) is studied after its high-energy milling in a planetary ball mill. The effects of the mechanochemical synthesis of composites during sintering and the structural features of the sintered bronzes are considered. The relation between the tin content and the formation of grain-boundary segregation and their influence on the properties of the synthesized materials are shown. For example, an increase in the tin content promotes an acceleration of grain-boundary interactions and a decrease in the bulk diffusion rate followed by the formation of supersaturated bulk and grain-boundary solid solutions. For a mixture composition with 18–20 wt % Sn, the grain-boundary tin supersaturation during mechanochemical synthesis increases by more than 2 times, which provides precipitation hardening of the materials sintered from the powders and ensures their microhardness in the range 2.1–3.0 GPa in the temperature range 20–800°C.
