Ri E. K., Ri Khosen, Yermakov .., Khimukhin S.N., E.A. Dmitriyev, Rybalkin A.A. Management of properties and structure of cast iron by modifying low carbonandelectropulse processing of melt
The article deals with the problem of possible structure and properties control of low chromium white cast-iron by means of its modification and electro-pulse treatment with subsequent modification. Kinetics and mechanism of the modification effect are described on the basis of the results of elements microanalysis in different cast-iron structural components. Electro-pulse treatment of melt being done before modification, the hardness and micro-hardness of structural components of cast-iron increases significantly due to the intensification of phase separation processes of cast-iron components. Wear and heat resistance of the modified chromium cast- iron also increases.
Keywords: Modification, electro-pulse treatment, crystallization, structure formation, hardness, micro hardness, wear resistance, oxidation resistance.

In the first part of the work shows that during solidification of Al alloys 15...30%Si it is possible to form patterns with small allocations of the Si-phase (eutectic) and large (primary and secondary crystals). The methods of heat treatment, which allows to obtain the structure that meets the required mechanical properties. The correlation between structure and thermal expansion of the studied alloys. Responsible for the formation of structure and properties of alloys proposed as hydrogen. On the example of the alloys Al30...50%Si shows the possibility of creating a new strain of materials with low values of the coefficient of linear expansion, low specific weight and excellent mechanical properties.

Nikitin K.V., Nikitin V.I., Yerisov Y.A., Fedotov A.V. Hereditary influence of deformed waste on the physical properties of grade 1420 alloys
The hereditary influence of the strain of waste on the density and electrical conductivity of the alloy 1420 (AlMgLi) was studied. It is established that the alloying of aluminium elements with large values of the solubility criterion (Mg, Li) causes increased tendency of the alloy to the inheritance patterns of the initial charge. Samples obtained from the deformed plates of 2 mm thickness, had higher values of density in liquid and solid States. The electrical conductivity was changed by a reverse law: with a decrease in the degree of deformation of the initial charge was increased the electrical conductivity before and after single remelting.
Key words: Alloy 1420, the system AlMgLi, the solubility criterion, structural heredity, strain the mixture, density, electrical conductivity.

Compositions of aluminum-zinc alloys are offered for soldering of assemblies of radio engineering appointment. It is shown that increase of the zinc content in an aluminum alloy, in proportion reduces temperature of its melting and increases its mechanical properties, while maintaining high plastic properties that allow processing these alloys with high extent of deformation. The structure of the received alloys has the eutectic type that gives to alloys high castability which provides high solder properties.
