Marukovich E.I., Stetsenko V.Y. Scientific problem of metal melts. Solutions
In the existing theories of liquid state of met¬als and alloys the basic structural element is atom. It creates a serious problem in scien¬tific understanding of the mechanism of pro¬cess of melt and properties of metal melts. For the solution of this problem it is neces¬sary 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 sys¬tems consisting on average for 97% from nanocrystals and for 3% – from atoms which form an unstructured zone.
Key words:Melt, nanocrystal, crystallization centers, at¬oms, microchip, clusters, metals, alloys.

Chaikin А.V., Chaikin V.А., 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 techno¬logical process for the diffusive deoxidazing of steel 20GFL for wagon casting production with the help of a dispersive diffusive alu¬minum deoxidizer. The application of REM (rare earth metals) allowed to refine the met¬al 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 techno¬logical process has been implemented at the AO «Altayvagon» Rubtskov branch.
Key words:Steel, slag, statistical analysis, inoculants, defusive deoxidizing.

Titov V.I. Phase analysis in research structure – properties of high-strength steels for aircraft equipment
With the help of the method of phase phys¬ico-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 400…500°C with 1000-hour heating the material is strength¬ened and the levels of impact strength and resistance to stress-corrosion cracking de¬crease. At a temperature of 450°C, an a–Cr phase forms, which reduces the properties of the material. It is proposed to reduce the temperature of heating the steel for quench¬ing from 900 to 830°C, which made it pos¬sible 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 pro¬cess.
Key words:Phase physicochemical analysis, martensitic aging high-strength steels, phase composi¬tion, mechanical properties.
