Poddubny A.N. The factors determining the hardness and wear resistance of Fe-C alloy castings
When studying the physical resistance of Fe-C alloys under conditions of the abrasive wear, there is a wide-ranging discussion to determine the main factors affecting the resistance of products made from these alloys. The main subject of the research is the role of the structures being a part of Fe-C alloys and their effect on the general abrasive wear resistance of products. For products of this type and the structural state of alloys, the microhardness of the metal base, which determines the carbide fixation strength and the general wear resistance of parts, is the determining factor to ensure high abrasive wear resistance.
Key words:Hardness, wear resistance, metal base, abrasive wear, carbides, martensite, decomposition of austenite.

Key words:Induction melting, alloys Al-Gd, structure, properties, ductile cast iron, high aluminum ductile cast iron, gadolinium.

Mukhomorov I.A. About dimensional accuracy of castings
The article lists the reasons affecting the dimensional accuracy of castings. Recommendations for the control of dimensional accuracy of the castings are provided. Parameters of the molding composition needed for production of castings with the required dimensional accuracy are given. The causes of casting strains of castings are shown.
Key words:Castings, dimensional accuracy, molding composition, gating system, casting strain, manufacturing accuracy of the equipment, adjustment, models, pallets, molding equipment.

Vasenin V.I., Bogomyagkov A.V., Sharov K.V. Definition of the hydraulic resistance of the feeder in the ring-shaped gating system
It is determined the fall in 1.5 once coefficient resistance turn stream fluid in feeder at give fluid to feeder in two side by comparison with one-sided give. It explaines appearance second whirlpool district and summary lowering resistance thesis two districts simile by one-sided give.
Key words:Pouring basin, sprue, collector, feeder, head, resistance coefficient, expence coefficient, stream speed, consumption of liquid

Iksanov M.V., Golod V.M. Computer thermodynamic analysis of Ti–Al–V cast alloy
The possibility of determination of the thermophysical and physico-chemical characteristics of alloys by means of thermodynamic simulation taking into account the disequilibrium degree of the crystallization process occurred during solidification and cooling of castings in the mold is shown.
Key words:Titanium alloys, properties, simulation.

Desnitsky V.V., Desnitskaya L.V., Matveyev I.A. Creation of a casting technology for production of critical steel parts
In the operation of critical parts, such as railway castings, there are cases of a reduction in the load-carrying capacity of structural components as a result of the action of a combination of factors such as corrosion, reduction of fatigue strength, etc. For this reason, the short-term mechanical properties of specimens cut out from castings cannot describe the strength of the whole article, and the service life depends more on ductility of the material. In the course of this work, the casting technology for production of critical steel parts was created by combining the results of the analysis of solidification processes simulation and the operation of the cast part.
Key words:Fatigue cracks, simulation, steel castings, vacuum-film process.

Tkachenko S.S., Emelyanov V.O., Martynov K.V. Conditions for filling the macrorelief of apress-mold with a model composition using the free casting method
The results of a full-scale modeling of the investment casting process as applied to filling the press-molds with a model composition using the free casting method are presented. Surface phenomena at the edge of the flow front are discussed.
Key words:Investment casting, wetting angle, art castings, surface roughness.

Andreev V.V. About manufacture of double-layer iron mill rolls with the use of centrifugal machines with a vertical rotation axis
The possibilities and prospects of the technology for manufacturing double-layer iron mill rolls with the use of centrifugal machines with a vertical rotation axis are considered. It is shown that hollow low-height billets, including double-layer vertical rolls, can and should be cast by the classical method with the use of spindle-typecentrifugal machines with a vertical rotation axis. Production of large-sized, long(high) and solid billets, including double-layer sheet rolls using the centrifugal machines with a vertical rotation axis is impractical.
Key words:Mill roll, cast billet, iron, working layer, core, structure, centrifugal machine.
