Kolokoltsev V.M., Goltsov A.S., Stoliarov A.M. Choice and Rationale of New Heat-Wear-Resistance Iron
Analysis of steels with chromium content 17…24% and complex-alloyed white irons with chromium content 18…28%, which simultaneously have high heat-resistance, abrasive and impact-abrasive wear resistance, corrosion resistance was carried out with the purpose of sound choice of alloy working in conditions of wear and high temperatures. Properties of researched alloys in cast condition and after high-temperature oxidation t = 800 and 1000°C are got and elaborated. Rational quantities of complex-alloyed white iron's alloying elements for receipt of castings with high heat-wear-resistance properties, which operate in conditions of abrasive and impact-abrasive wear resistance and high-temperature oxidation t = 800…1000°C, are identified. Key words: heat-wear-resistance alloy, complex-alloyed white irons, high-temperature oxidation, corrosion resistance, casting properties.

Kondratyuk S.Ye., Stoianova E.N., Shcheglov V.M., Prymak I.N., Parchomchuk Z.V. Hereditary Modification of Cast Steels
By introduction of additives with fine crystalline structure and same chemical composition into the melt the possibility of modification of 45Л and Р6М5Л cast steel structure is shown. The additives are formed with the rapid cooling crystallization. Such additives maintain their inherited properties in the melt, initiating formation of large quantity of nucleation centers for crystallization and providing uniform fine grained structure over cross-section of the castings. Key words: steel, inheritance, melting, crystallization, structure formation.

Kulakov B.A., Dubrovin V.K., Karpinskiy A.V., Chesnokov A.A. Gating Induction System Installation of Centrifugal Ceramic Crucible
The paper deals with the processes of pouring a melt from a ceramic crucible to the mould cavity in induction centrifugal melting and pouring machines. Effect of the frequency of crucible and mould rotation, as well as of the position of working cavities on the character of melt flow, filling speed and time of mould filling is also considered. A technique for calculation of the sections of gating system elements is presented. Key words:Melting and casting plant, centrifugal casting, ceramic crucible, gating system, calculation of gating system, mould, pouring, casting.

Tikhomirov M.D. New and Traditional Methods of Computing Tasks of the Theory of Casting Processes by the Example of the Casting Process Computer Simulation System "PolygonSoft"
Discussed are advantages and disadvantages of using the SPH and FEM when simulating casting processes in the "PolygonSoft" system. It is concluded that the development of the casting process computer simulation system should be in the field of rational combination of traditional design methods (such as FEM), considering the possibility of speeding up the designs by means of video cards and new methods (such as SPH), allowing to use fundamentally new "networkless algorithms". Key words: casting process simulation, casting process computer simulation system "PolygonSoft", finite elements method, solidification, crystallization, hydrodynamics, pouring, SPH method, networkless method of smoothed particles.
