Demidovich V.B., Khatsayuk M.Y., Timofeev V.N., Maksimov A.A. Numerical simulation of titanium alloy non-crucible melting in the alternating electromagnetic field
By the integration of ANSYS and Fluent the numerical model of the cylindrical halffinished product melting process in the alternating magnetic field was developed. The calculation of the melting process was implemented by enthalpy porosity methodology with the use of turbulent flows k-? SST in the unsteady state. Electromagnetic sources of movement and heat were defined by the method of solution of finite element harmonic problems on magnetic vector potential in the inductor ingot system at each iteration of hydrodynamic problem. Basing on the developed model the calculation and analysis of physical processes during titanium alloy (6Al-4V) non-crucible melting was made.
Key words: Titanium alloys, magnetohydrodynamics, crucibleless melting, metallurgy, induction heating.

Poluboyarov V.A., Korotaeva Z.A., Zhdanok A.A., Gorbunov F.K. Modification of grey cast
Experiments involving modification of cast iron manufactured in China which is similar to Russian grades (SCh-18...SCh-30) using the compositions based on a mixture of tungsten and titanium carbides were carried out. Nanodispersed carbide powders were obtained by means of self-propagating high-temperature synthesis (SHS) in combination with preliminary mechanical activation (MA). The use of modifying agents for intra-mold modification may lead to an increase in the tensile strength up to 18.5%, relative corrosion stability in hydrochloric acid up to 58.8%. After modification in ladle, the strength of the samples increased to 25...29% only after storage for 3.5 months.
Key words: Modification, titanium and tungsten carbides, corrosion stability, protector metal, mechanical activation, tensile strength, hardness.
