Ten E.B., Batyshev A.I. Improving the efficiency of the Fe-Si-Al alloy Sendustmelting and casting technology. Part 2. Improving the melting technology
The factors allowing an increase in the efficiency of melting of Fe-Si-Al alloy Sendast are studied. First of all, it is proposed to eliminate the sequential melting of Fe-, Siand Al-bearing components. The basis share of the initial charging should be compact; the lumps of pure iron are better than powdered carbonyl iron, and the silicon steel wastes are even more preferable. In case of absence of such materials, the joint charging of Feand Si-bearing components is possible to conduct melting. In order to prevent overheating of the melt, the doping of the alloy with Al at the end of melting process should be carried out cyclically by introduction of small portions of aluminum and turn off of the furnace until the added portion of Al is dissolved.
Key words: Fe-Si-Al soft magnetic alloy, induction melting, melting of the charge, oxidation of components, reduction in loss of elements, reduction of total metal loss.

Marukovich E.I., Stetsenko V.Y. Scientific problem of modifying of primary crystals of a ?-phase of castings from silumin. Solutions
It is shown that intermetallic compound of the modifying ligatures are not crystallization centers of primary crystals of a ?-phase. As the main demodifier serves the hydrogen dissolved in liquid alpax. For a solution of the problem of modifying of primary crystals of a ?-phase in castings from alpaxes it is necessary to accept that crystallization centers of primary crystals of a ?-phase are the crystalline educations consisting of ?-phase nanocrystals, and the role of the modifying intermetallic compound of modifiers comes down to the active absorption of the dissolved hydrogen.

Kazakov A.A. Peculiarities of the control of metallurgical heredity in steels and alloys
On the example of a wide range of steels and alloys, as well as various technologies for their production and processing, the role of metallurgical inheritance to control the structure and properties of these metallic materials has been shown. The nonmetallic inclusions, as well as chemical and structural inhomogeneities, formed during the crystallization and solidification of steels and alloys, determine the nature of metallurgical inheritance. Examples of improving known and developing new steels and alloys, as well as technologies of their production, based on the control of metallurgical inheritance have been demonstrated.
Key words: Metallurgical inheritance, nature and control, steel, alloys, solidification, inhomogeneity.
