Marukovich E.I., Stetsenko V.Y. Melting and casting of silumins – nanostructural processes The existing theories of liquid state, crystallization and modifying of fusions don't allow to investigate difficult physical and chemical processes of melting and casting of silumins. To investigate these processes, it is necessary to consider fusion consisting of thermodynamic stable nanocrystals of phases and unstructured atomized zones. As a result of the conducted researches it is established that melting and casting of silumins are nanostructural processes. In these processes the major role is played by the centers of crystallization of phases, nanocrystals of aluminum and silicon, the dissolved and adsorbed hydrogen and oxygen.
Key words: Melting, casting, silumins, modifying, nanocrystals, centers of crystallization, nanostructural processes.

Afanasiev V.K., Dolgova S.V., Popova M.V., Magazov V.S., Chernysh A.P. On the new understanding of pure iron microstructure
It is proposed to assume that hydrogen, carbon, nitrogen, and oxygen are part of a single community HCNO – body, which forms a dark structural components in pure iron. The study of preparation of thin sections with different etching time in the conventional alcohol solution HCNO at low exposure time to 6 minutes provides a sharp high travelmasti sections. At high exposures the mass of the dark is replaced by light of education. The results show that we should spend a complex of works on heat and chemical-heat treatment of pure iron with the aim of obtaining iron with the maximum amount of dark or light that will allow you to adjust the properties of iron and alloys Fe–C in wide limits.
Key words: Common HCNO, pure iron, microstructure, etching.
