Afanasev V.K., Dolgova S.V., Kopytko A.A., Starostin M.A., Lavrova N.B., Chibryakov D.M. A new way of decontamination of metals and alloys
In job the new way of decontamination of metals and the alloys is presented, allowing essentially to increase durability and plasticity on the developed concepts in general not deformable alloys. The developed way leads to deeper (in 2-7 times) to removal of hydrogen. Laws of influence contents of gases on strength and plastic properties are considered.
Keywords: decontamination, hydrogen, deformation, alloys, properties

Prudnikov A.N. Formation of Eutectic Structure in Al-20%Si Alloy during Crystallization
The opportunity of increase of mechanical properties from hypereutectic silumin due to use of ways of crystallization providing processing of liquid metal hydrogen and holding in a firm-liquid condition with the subsequent training in water is shown. It is established, that due to formation in the central zone of ingots "pseudoeutec C tic" structures it is possible to increase hardness hypereutectic silumin in some times.
Keywords: silumin, crystallization, structure, eutectic, silicon, crystal, properties.

Chernyshov Y.A. Effectiveness of Electroslag Technologies in Casting Production
Some aspects of electroslag technologies and their capabilities in terms of metal quality assurance are discussed. Advantages of new methods of electroslag feeding are shown. Key words: electroslag technologies, metal quality, directional solidification, ingot mold, sand mold.

Brazovsky V.V. et al. Optimal Composition of Charge Mixes for Making Filtration Materials Charge compositions prepared on the basis of iron and aluminum oxides - aluminum and alloying additions have been developed. Structure and phase composition of synthesis products have been investigated, comparative characteristics of properties of porous materials are given.
Key words: self-propagating high-temperature synthesis, filtration material, combustion, powder mix, charge material.

Eskin G.I. et al. New Trends in Casting Technology and Deformation of Hypereutectic Silumins
Hypereutectic silumins are a new class of Al-Si composites with 16…22% Si. Such alloys differ from hypoeutectic and eutectic silumins by their high wear resistance and other characteristics that are important for the piston pair of internal combustion engines, in aircraft industry and for pipes in oil-and-gas complex under the conditions of a sharp temperature gradient and in aggressive media.
As a result of ultrasonic treatment of the melt and using new inoculants of the Al-Fe-P and Al-Cu-P types it was possible to effectively refine the structure of hypereutectic silumins and produce ingots by continuous casting with a satisfactory ductility for subsequent forming.
Key words: hypereutectic silumins, ultrasonic treatment, continuous casting, forgings

Sjцgren Torsten The deformation behavior of cast iron
For example, grey iron with high graphite content is not as strong as grey iron with a lower graphite content. With the research described in his doctoral thesis, 'Influences of the graphite phase on elastic and plastic deformation behaviour of cast irons', the author has studied the relationship between the morphology and amount of graphite that cast iron contains and the mechanisms that determine deformation characteristics. The research was conducted at Daros Piston Rings AB in Sweden during 2002…2007.

Shevchuk S.A. et al. Measuring Iron Casting Hardness with Poldi Hardness Gauge
Utmost simplicity of design, availability and versatility of Poldi hardness gauge predetermined its wide application in industry. The same explains numerous attempts of improving it to achieve a higher accuracy of measurements. Two main causes of systematic errors of Poldi hardness gauge have been found: dependence of measurement results on the operator's impact force, and on the difference between the hardness of the reference and that of the product being tested. The first cause can be eliminated by increasing the reference width, and the second one - by introducing the necessary

Cherepanov A.I. et al. Effect of Phase Contact Area and Inclusions on Strength of Cast Composites
Effect of phase contact area, quantity and type of inclusions on the strength of cast composites of the Al-Al2O3 and Al-Fe systems has been revealed. Based on original mathematical processing of results, methods of quantitative evaluation of the contribution of the phase contact area to the overall strength of cast composites is proposed. Key words: interphase boundary, inclusion, aluminum matrix, strength of cast composites.

Leonov V.V. Microhardness of trile solid solution Ni-Al-Ge on nickel basis
The microhardness HV, ГПа of trile solid solution Ni-Al-Ge on nickel basis from composition (X, ат.%) was investigated. Linear equation HV= 0,98 + 0,039XAl + 0,034XGe was determined.
Key words: microhardness, solid solution, nickel

Nemenenok B.M. et al. Harmful Emissions during Melting and Refining AK9 Alloy in Crucible Induction Furnaces
The process of dust and gas emission during melting AK9 alloy in IAT-2.5 and IAT-6 crucible induction furnaces has been investigated. It is shown that the highest dust level and contamination with gases is characteristic for the period of refining the melt with hexachloroethane and during charging the return from the high-pressure die casting area. Dispersiveness, X-ray diffraction and electron microscopic analyses of the forming dust have been performed. It has been established that the dust has a complex mineralogical composition, is polydisperse, which causes certain difficulties in collecting it.
Key words: dust and gas emissions, return, dispersiveness, refining, chlorides

Arjunwadhar S.H. et al. Energy savings and carbon credits. Opportunities and challenges for the foundry industry
Metal casting is one of the most energy intensive manufacturing processes. In particular a large amount of energy is consumed in the melting operation. Consequently adoption of energy efficient melting technologies by foundries is a win-win option; improvements in energy efficiency not only reduce energy costs, but also have the potential of generating additional revenues through sale of carbon credits. Seeking carbon credits by developing appropriate clean development mechanism (CDM) projects based on energy efficiency improvements promises benefits for Indian foundries. While the primary benefit of the CDM project would be the savings in energy, additional revenues through sale of certified emission reductions (CERs) could help improve the project returns.
