Mechanisms of influence of modifiers on crystallization of tin and aluminium bronzes

It has been shown that elementary crystalline cells of α‑phases of tin, aluminum bronzes and main modifying phases do not correspond to the principle of structural and dimensional correspondence of Dankov‑Konobeevsky. Modifying structures in tin and aluminum bronze castings is a nanostructured process. The main role of tin and aluminum bronze modifiers is to significantly reduce the concentration of adsorbed hydrogen, which prevents the formation of crystallization centers of α‑phase microcrystals in castings when they solidify.
