Skripnik S.V. Blank Production by Electroslag Remelting of Risers from Heat-Resistant Materials
Possibility of producing machine-building blanks by remelting heat-resistant 20X13 steel waste in the form of large ingot risers is shown. A two-circuit remelting scheme using non-consumable electrode and the consumable oneis proposed. Such manufacturing scheme allows to regulate remelting speed and to break the existing in the canonical scheme of the electroslag process (ESP) link between electrical parameters and process performance.
Key words: electroslag process, risers, ingots of heatresistant steels, two-circuit scheme.

Sysoyev O.Y., Yafeng Xu Prediction of State of Material Structure at Cyclic Loadings by Acoustic Emission Signals
Presented is a complemented physical model (PM) of material structure change at long acting alternating loadings in consideration of informativity of acoustic emission (AE) parameters and correspondence of substructural material transformations at cyclic loadings to mesoscale levels.
Key words: cyclic loads, material structure change, mesoscale levels, acoustic emission.

Ri E. K. , Ri Khosen, Statsenko D.P., Bulachok A.I., Khimukhin S.N. Effect of Aluminum on the Distribution of Basic Components in Structural Constituents of Chromium Iron
Distribution dependence of the basic components in the carbide phase and metallic substrate on the aluminum content in white chromic cast-iron is fixed. The possibility of crystallization of the secondary aluminum carbide Fe3AlCx as a part of eutectoid is shown, when aluminum content is more than 1.0 wt % in chromic cast-iron. The aluminum content decreases in the edges of primary austenite and eutectic austenite, although in the centre of excessive austenite it increases monotonously up to 2.0 wt % Al in white chromic cast-iron.
Key words:Austenite, crystallization, alloying, components, excessive and eutectic austenite, carbide.

Lepov V.V., Golikov N.I., Achikasova V.S., Loginov B.A. Steel Fracture Mechanisms in Different Structural States
By investigations of morphology of deformation surfaces of flat tensile specimens microstructural peculiarities of accumulation of damages and fracture character of nanostructured steel at low temperature have been revealed. Differences of brittle and tough-brittle fracture characters at room temperature and -40C have been found, however, at the temperature of - 60C appearance of some characteristic peculiarities of fatigue fracture have been noted.
Key words: brittle fracture, deformation, nanostructured steel, impact binding.

Kadyrbekova K.K., Saidakhmedov R.K. Properties of Chromium-Based Protective Nanocoatings
Chromium-based protective nanocoatings applied to metal and non-metal substrates were investigated. A conclusion of wide possibilities of using Cr coatings vacuum-deposited by magnetron sputtering instead of galvanic coatings was made.
Key words: protective coating, surface relief, magnetron sputtering, nanoparticles.

Afanasyev V.K., Prudnikov A.N., Gorshenin A.V. High-Strength Aluminum Alloy for Aircraft Unit Parts
On the basis of system AlSi the high-strength alloy is developed for details of units of flying devices. On a level of mechanical characteristics (?, ?, ?-1), and also wear resistances the skilled alloy considerably exceeds a level of alloy 12 now in use, and possesses smaller relative density and temperature factor of linear expansion in an interval 2050C.
Key words: alloy, silumin, structure, mechanical properties, wear resistance, relative density.

Martynyuk A.M., Krupin Y.A. Effect of Aluminum Foam Structure on Materials Compressive Strength
Effect of the structure of foam aluminums metal frameworkon its mechanical properties was investigated. Relationship between the characteristics of foam aluminum structure and the degree of its deformation has been established. A phenomenological model of framework structures behavior at compressive testing has been developed.
Key words: foam aluminum, structural material, cellular solid body, elastic deformation, strain.
