Gabets A.V., Sukhov A.V., Filippov G.A. Special Inoculated Alloyed Iron for Friction Wedge of Bogies
There was conducted a comprehensive study of the effect of alloying and inoculation on the mechanical properties, wear resistance and structural state of SCh35 iron used as a material for the friction wedge of vibration dampeners in wagons. It was shown that iron inoculation with Ni and Mo, in combination with inoculating additives, improves its hardness, strength and wear resistance, which allows to reduce materials consumption of the friction wedge.
Key words: Gray iron, alloying, inoculation, hardness, wear resistance, friction wedge of bogies.

Kuksa A.V. Porous castings with using as a pore-forming material polystyrene granules
The article shows technological schema of sheathing polystyrene granules by liquid glass shell and dusting by dispersed powders: aluminum, alumina or cristobalite and other; shows constructionally-technological schemata of designed and tested technical solutions (metal moulds) for producing porous castings by vacuum impregnation with using as a pore-forming material polystyrene granules which plated by reinforce shell and blank spherical shells. For the first time was obtained samples of porous castings of silumina, zinc and lead, shown their photographs. Visualization of thermal impact on polystyrene granules with reinforcing shell is shown that they became the hollow shells, while retaining the spherical shape and hardening.
Keywords: Polystyrene granule, sheathing, reinforcing shell, a device for impregnating, pore-forming material, blank spherical shells, model of porous castings.

Solovko I.T., Shinsky I.O., Berdyyev K. Prefoaming Original Polystyrene in UV Radiation
Proposed is a new cost-effective method of prefoaming polystyrene (PS) granules in UV radiation to make expanded patterns in the foundry. Regimes of prefoaming original PS in UV radiation have been determined experimentally. Based on the results obtained, an experimental unit for foaming PS by the new cost-effective method has been designed.
Key words: Prefoaming polystyrene granules, UV radiation, foam pattern, expanded pattern casting.

Issagulov А.Z., Kulikov V.Yu., Laurent Сh., Tverdohlebov N.I., Shcherbakova Ye.P. Improved method for producing cast billets casting method on gasified models
The basic technological molding factor in expanded pattern casting has been determined. Production of quality castings by expanded pattern method, like all metal casting technologies, depends on many technological factors. Since in expanded pattern casting crucial is the pattern quality factor, and the pattern cost, especially in individual casting production, may substantially influence the casting production costs, the molding and pouring operations must be carried out carefully in order not to damage the polystyrene pattern.
Key words: Expanded pattern, casting.
