Dorofeyev G.A., Komarov A.A. About changes of balance of carbon in troops of synthicom in arc-steel-steel fuel
The process of electric melting in an arc steel smelting furnace of 20 tons of synthicom CK15 grade was studied, an analogy was made with melting of 20 tons of cast iron with a carbon content of 4.5 percent. An indicator of the value of the consumption of synthicom in the case of replacement of cast iron with an identical amount of carbon introduced by these materials into a metal bath during the melting of the metal scrap is calculated. The positive sides of active oxidation and removal of carbon from the bath are determined and the negative effects of excessive oxidation of carbon at the concentration of carbon in the metal to the beginning of refining below the level of 0.10%.
Key words: Electric melting, synthicom, carbon oxidation, composite materials for the production of steels, carbon content.

Titov V.I. Development of methods for analyzing the alloys of Ti-Zr, Ti-Mo-V-Al
As a result of carried out scientific research and experimental work, it has been shown that high contents of zirconium and molybdenum can be determined in titanium alloys of Ti-Zr and Ti-Mo-V-Al systems. For the contents of 10…20% molybdenum in titanium alloys above the above systems, a differential-photometric method has been developed. It is established that the titanium matrix does not affect the magnitude of the signal in the determination of molybdenum, which made it possible to construct a calibration curve at the last stage of the analysis on a standard molybdenum solution. The result of the research is the developed methods for determination of zirconium (40%) and molybdenum (10…20%) in titanium alloys of Ti-Zr and Ti-Mo-V-Al systems.
