Marukovich E.I., Stetsenko V.Y. Scientific problem of metal melts. Solutions
In the existing theories of liquid state of metals and alloys the basic structural element is atom. It creates a serious problem in scientific understanding of the mechanism of process of melt and properties of metal melts. For the solution of this problem it is necessary to read that the basic structural element of liquid metals and alloys is the nanocrystal. As a result of researches it is set that metal melts are the equilibrium two-phase systems consisting on average for 97% from nanocrystals and for 3% from atoms which form an unstructured zone.
Key words:Melt, nanocrystal, crystallization centers, atoms, microchip, clusters, metals, alloys.

Chaikin .V., Chaikin V.., Kolpakov V.V., Maslov D.V., Zakoptelov E.P. Applying dispersive deoxidizing mixtures for increase of steel 20GFL qualitive indicators
The article describes benefits of the technological process for the diffusive deoxidazing of steel 20GFL for wagon casting production with the help of a dispersive diffusive aluminum deoxidizer. The application of REM (rare earth metals) allowed to refine the metal more effectively, to increase the stability of the toughness of steel with an acute cut at the negative temperature, and to reduce the cost of castings. The described technological process has been implemented at the AO Altayvagon Rubtskov branch.
Key words:Steel, slag, statistical analysis, inoculants, defusive deoxidizing.

Zolotukhin V.I., Gordeyev E.I., Provotorov D.A., Golovko A.G. Complex solutions of the Vulkan-TM Company for metallurgical and foundry production industry
Some examples of the developments of the SME Vulkan-TM for pouringand out-of-furnace processing of metal at metallurgical enterprises and foundries are given. The flexibility and modular configuration of the products offered, including those made on individual orders, ensures their easy adaptation to any production conditions.
Key words:Molded refractory, bottom blowing, stopper ladle, wire feeding machine, slide gate, monolithic ladle lining.

Titov V.I. Phase analysis in research structure properties of high-strength steels for aircraft equipment
With the help of the method of phase physico-chemical analysis, the nature of phase separation during long-term operational heating of high-strength martensitic aging steels has been established. It is shown that in the temperature range 400500C with 1000-hour heating the material is strengthened and the levels of impact strength and resistance to stress-corrosion cracking decrease. At a temperature of 450C, an aCr phase forms, which reduces the properties of the material. It is proposed to reduce the temperature of heating the steel for quenching from 900 to 830C, which made it possible to reduce the supersaturation of mar-tensite by chromium and molybdenum by binding the alloying elements to the phases l1 and ? formed during the quenching process.
Key words:Phase physicochemical analysis, martensitic aging high-strength steels, phase composition, mechanical properties.
