Khudokormov D.N. et al. Semiconductor Effect in Cast Iron Graphitizing.
Peculiarities of producing spheroidal inclusions of semiconductor phases in different alloys, including cast irons, are analyzed and compared. It has been shown that the spheroidizing elements added to alloys are foreign donors for such semiconductors. By the example of graphite formation in cast irons the mechanism of graphite inclusion spheroidizing and causes that determine the formation of vermicular graphite inclusions are explained.

As applied to the faced metal mold casting, the composition of alloyed cast iron for automobile engine cylinder liner has been optimized. The mastering of the developed alloy and the alloy making process at Lidsky LMZ Company have allowed not only to improve the quality characteristics of the material, but also to cut costs of alloying additives by using secondary resources.

Zemskov I.V. et al. Recycling Steel Waste at Machine-Building Plants.
A process of recycling carbon, low-alloyed and high-alloyed steels in grades st3, 20Г, 40Х, Р6М5, 20Х13, and 12X18H10T comprising remelting in an induction melting furnace, pouring at a semicontinuous casting plant, heat treatment, and, if necessary, plastic deformation, has been developed. Thermal and process parameters of semicontinuous pouring under the conditions of foundry shops and areas at machine-building plants are given. Properties and structure of steels in cast and deformed state (50% and 80%) have been analyzed. It has been shown that the steel properties in continuous castings in cast and heat-treated state meet the corresponding GOST requirements.

Zadrutsky S.P. et al. Refining and Inoculating Aluminum Alloys.
The authors discuss the mechanism of refining, degassing, inoculating of aluminum-based alloys. Based on investigations conducted at the Cast Alloys Metallurgy Department and together with the Evtektika Research-and-Production Enterprise the production of various preparations for furnace and out-of-furnace alloy treatment has been mastered. The preparations differ from conventional ones (hexachloroethane, zinc chloride and others) by ecological compatibility, manufacturability and high stability. Based on these preparations processes of casting manufacturing using secondary aluminum alloys have been developed.

Kalinichenko S.A. et al. Reduction of Negative Effect of Increased Iron Content in Aluminum Alloys.
Processes allowing, to a certain extent, to neutralize the negative effect of iron on mechanical properties of silumins have been developed. This, in its turn, allows recycling secondary Al alloys contaminated with iron for using them in the production of quality castings.

Galushko A.M. et al. Development of the Process of Refining Aluminum Alloys with Powdered Sulfur in a Nitrogen Jet.
A plant for refining aluminum alloys with powdered ingredients in a jet of a neutral gas has been proposed. Effectiveness of the refining is achieved by combining the melt treatment with a flux and blowing with a neutral gas, which provides a high degree of degassing and removal of solid nonmetallic inclusions. The refining process has been commercially tested in making aluminum alloys from low-grade charge materials.

Application, brief technical description and main performance characteristics of the thermal analyzer are given. Results of PC processing of the thermograms obtained with the aid of the described device are given.

Mikhaltsov A.M. Gas Dynamic Processes in Investment Casting.
Questions of capturing air in the pressing chamber and die cavity ventilation in investment casting have been discussed. It has been shown that taking into account air friction on channel walls the estimate issue rate decreases by many times as compared to the issue through an opening in a thin wall. Formulas for calculating the area of ventilation channels taking into account the gas evolution of the parting lubricant are given.

Zemskov I.V. et al. Vertical Continuous Casting of Iron Blanks.
Results of mechanical properties and structure of continuously cast blanks of gray antifriction high-strength and alloyed iron are presented. In all cases of using inoculation it is possible to produce the necessary iron structure whose mechanical properties meet the existing standards. Along with that, the labor consumption of casting manufacture as compared to conventional methods is reduced, metal yield is increased, machining allowances are decreased. It is shown that the method of vertical continuous casting can be used with no limit in foundries of machine-building plants.

Ovchinnikov V.V. Ensuring Reliable Adhesiveness of a Strengthening Insert with Aluminum Base of Bimetallic Pistons.
Demands on the cylinder-and-piston group component materials have been toughened. It is optimal to produce bimetallic pistons with a strengthening insert, but the process of their manufacture is complicated. In particular, aluminizing of inserts is used. Besides, to produce diesel engine pistons by metal mold casting, an original gating system has been designed, which creates conditions for the directional crystallization of the melt, avoiding unfusion at the neresist-aluminum boundary.
