Afanasyev V.K., Popova M.V., Gorshenin A.V., Dolgova S.V., Herzen V.V. The nature of plastic deformation of alloys Al–1…50% Si
The processes occurring during plastic deformation in alyumin-silicic alloys. The formation of eutectic and primary is associated with the presence of silicon in the alloys of hydrogen and nitrogen. Fragility alloys Al–Si proposed as a form of hydrogen embrittlement. Hot plastic deformation is degassing alloys due to the joint application of temperature and pressure. Decontamination techniques developed, allowing to obtain a structure approaching the solid solution due to the application of cyclic pressure and temperature (hot forging and rolling). The prospects of creating a new generation of deformed alloys of Al–Si multi-purpose.
Keywords:Hydrogen, degassing, deformation, alyuminsilicic alloys, mechanical properties, microstructure.

Dudchenko A.V., Tarasevich N.I., Primak I.N., Shcheglov V.M. Selection of a Rational Method of Feeding Metal to a Mold at Speed Pouring
The results of researches, exposing character of influence of construction of the gating system on the hydrodynamic speed modes features of the filling, distributing of metal streams and thermal mode of the form in the process of filling and after its completion, are resulted. It is set with the use of method of computer design that the increase of speed of the filling lays on certain limits on the use of the generally accepted constructions of the gating systems. Most it follows the full satisfying requirements of the speed modes of fill-out to count the method of admission of metal in a form through the siphon gating system.
Key words:Direct and return riser, bottom feed of metal, large castings, hydrodynamics.
